i have a serious problem in Magento Admin Backend. After login its shows a BLANK Page. i used the same files and database in different server, there it was working fine but when i have transferred files into LIVE then Admin issues came. Please help me over this as i got frustrated from last some dayz. If you need any more dertails then plz ask but i need to resolve this soon. Link: http://studywings.com/index.php/admin/
Magento ver: 1.7
flush your magento root /var/cache folder and /var/session folders, It may have previous server session that may cause problems.
Otherwise disable all third party modules and try again. I think this will help
I had the Same problem,
i have also debug the any errors occured, i tried index.php file
ini_set('display_errors', 1);
error_reporting(E_ALL);
$_SERVER['MAGE_IS_DEVELOPER_MODE'] = true;
pleced above code in index.php file. after that i have tried admin login.
showing the errors are session related, header already send errors.
i have to add the code in root/index.php file in top add the following line.
ob_start();
after that tried the login its worked.
Cheers..!
Is url changes to this after click login button or not?
http://yourdomain.com/index.php/admin/index/index/key/(key value)/
if url changes but not not show the dashboard page then go to
app/code/core/Mage/Core/Model/Session/Abstract/Varien.php
make copy of this file
Find the code for setting session cookie parameters these started on line 77
Comment out the final three lines and be sure to remove the comma after $this->getCookie()->getPath(). You should end up with this:
// set session cookie params
session_set_cookie_params(
$this->getCookie()->getLifetime(),
$this->getCookie()->getPath()
// $this->getCookie()->getDomain(),
// $this->getCookie()->isSecure(),
// $this->getCookie()->getHttponly()
also line 104 comment out :
//call_user_func_array('session_set_cookie_params', $cookieParams);
If there is no change in url after click login then try to uncomment display error and see error_log file of your server
I think this problem is due to file permissions. As you added files from one server to another, permissions might be get changed.. Try to give the permissions to all the files. Check this http://www.mage-shop.com/forum/threads/3-Magento-Admin-Backend-Blank-Page-Error
There are a number of things that can cause it, but it's most common after migrating to a new server, last time it happened to me it was an excessively low php memory_limit setting on the new server - the Admin part of the site uses a lot more resources per user than the frontend.
In general when having this issue:
Flush out your cache by emptying var/cache
Clear out sessions by emptying var/sessions
Check the magento error logs/reports for an error code in var\logs and var/reports
Turn on magento error logs in mysql if logging isn't already on! (look in core_config_data for WHERE path like 'dev/log/active'
Check if your php configuration is displaying errors
Check your apache/php error logs for more clues - memory errors will show up here for example
Try this solution
It sounds like you want to enable Developer mode. Add this to your .htaccess file:
SetEnv MAGE_IS_DEVELOPER_MODE "true"
You may also want to enable display errors in index.php:
ini_set('display_errors', 1);
The best way I have found to debug is with X-Debug in a local environment. You can also use log files to help debug in a production environment, if your unable to run X-Debug in the environment.
I've got a more detailed posting here:
http://www.molotovbliss.com/debugging-tips-and-tricks-with-magento-commerce
Consider also installing XDebug
Hope this helps you!
Just to complete the other answers....
I am upgrading a magento install, and got the same problem, in the end I had another folder inside of var/
magento/var/minifycache
Only worked after clear deleting the files inside of this folder.
I had the same problem after uninstalling an extension. I thought that clearing cache would be enough, and I did without success... later speaking with the technical team, they commented me that it did not work because I hace memcache installed, and needed to be done the cleaning via system - backend (that i coudl not see...)

I have an installation of Magento 1.9.2. I am using a custom theme, and anytime I try and place an order it kicks off the Ajax on the page and then stops with no error messages, but does leave a log:
ERR (3): User Error: Some transactions have not been committed or rolled back in /html/lib/Varien/Db/Adapter/Pdo/Mysql.php on line 4039
I have spent 2 days trying to get to the bottom of this with no joy. It doesn't matter what payment method I use its always the same.
You should try to log all MySQL queries to see what wrong here. lib/Varien/Db/Adapter/Pdo/Mysql.
Open the file lib/Varien/Db/Adapter/Pdo/Mysql.php and change the value of the protected property $_debug to true. You can also change the value of $_logQueryTime which is especially handy when debugging slowdowns. Once you make this change all queries will be logged in the file var/debug/pdo_mysql.log
Hope this will help you. Please put your corrupted query here if you fixed it.
I had today the same problem. Magento 1.9.2.4 with a custom theme. Everything worked fine, expect the checkout-process. The custom theme used the PHP short open tag <? php code ?> . After enabling short_open_tag in the php.ini, everything works fine.
My Magento web site home page has a redirect loop error. When I try to open it it goes to my old server url and gives the error:
The webpage resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.
When I try to go into admin it takes to me old server admin url without any error.
I down loaded the fresh data base and connected my store to that it works fine but when i connect it my old data base it give same error.
Please advise me.
This isn't an ideal solution, but I was having issues with Magento 1.9.x.
The setup was: Nginx Proxy & SSL Terminator => Apache Webserver
No matter what I did enabling SSL caused a redirection loop. I narrowed the issue down to Magento rather than the Nginx configurations.
It was like Magento didn't know it was receiving a secure connection from Nginx even though the correct headers were set.
The dirty solution was to add some code to the very bottom of index.php within the magento root directory (ie. /var/www/magento) just before the Mage::run... line, like so:
if( isset($_SERVER['HTTP_X_FORWARDED_PROTO']) ) {
$_SERVER['HTTPS'] = 'on';
$_SERVER['SERVER_PORT'] = 443;
}
Mage::run($mageRunCode, $mageRunType);
Wrong permissions can also cause this to happen. So in addition to truncating the var/cache and var/session folders, go ahead and make sure that you have the proper permissions on the app, skin, and includes directories, sub-directories and files. I believe the suggested permission setting is 644. You can do this with a proper FTP client such as FireZilla.
Go to table core_config_data
Update these value to be your localhost url(or whatever url you are providing while installation):
web/secure/base_url //(new url)
web/unsecure/base_url // (new url)
Empty the var folder.
I got it fixed.
I manually deleted my cache i was unable to login in my amdin and it get fixed
My issue was Cloudflare, put it in Development mode and it worked. It was cache related.
Issue: ERR_TOO_MANY_REDIRECTS - redirected you too many times
This issue is related cookie domain name.
For ex: if you already installed Magento 2 in www.example.com, and now you change magento base path to sub domain path like www.subdomain.example.com means, then you need to update your cookie domain entry inside of core_config_data table. You cannot access magento 2 backend so you can use following query to check record exist else use insert query.
SELECT * FROM `core_config_data` WHERE `path` REGEXP 'cookie_domain'
if record exit then update subdomain.example.com to the value column.
else
INSERT INTO `core_config_data` (`scope`, `scope_id`, `path`, `value`) VALUES ('default', 0, 'web/cookie/cookie_domain', 'subdomain.example.com');
Then flush cache using command php bin/magento cache:flush
Refresh magento 2 admin, now you can access admin. try this. thanks.
Note: if you are not using cookie domain, then don't configure this settings, if you configuration wrong then also you can face this error, so to fix that error update value to default configuration.
I had the same issue and after reloading and reloading my page I noticed that the error message responded to www.mydomain.tld and sometimes to mydomain.tld. I'm using Plesk on the server and I remembered that I set the Domain to always be called without www. I just changed that to none in the hosting settings of the domain. Lucky me, that solved that issue. Hope that helps someone else.
I moved website to new server, domain stay the same, files structure stay the same, but path to public_html has beed changed. Database has been also moved.
I tried to clean cache, but i dont think I made it. This is error i get:
Could not find action file at: /home/account_name/domains/domain.co.uk/public_html/manager/controllers/default/welcome.php
account_name is different now.
I havent access to the old server, so I cant login and clear cache. I tried to do it using php script I found, but it didnt help.
Moving to new server documentation - there is welcome.php error and how to fix it, but since I haven't access to website from old server, I can't do it.
Also I can't login and clear cache in admin panel, because this message in when i wan get access to it.
I also change in db, in modx_workspaces->path from {core_path} to home/account_name/domains/domain.co.uk/publis_html/core, but didn't help.
How can i clear cache or if it's not the case, what should I do to make it work?
Update
I have change location in settings:
config.core.php
connectors/config.core.php
core/config/config.inc.php
manager/config.core.php
In .htaccess I couldn't find path to website, I didn't change anything.
I remove all content from core/cache/, except one file (.gitignore), and if I go to domain.co.uk/manager/ it's blank page, no content at all. And still can't log in.
Clear the cache on the new server manually VIA FTP or from a shell.
Change that modx_workspaces thing back
did you change all your settings in core/config/config.inc.php ?? if not do so, that is where you will set most of your paths & database credentials.
you have a backup? good!
Now upgrade to the same version of modx, that should fix all your path issues. [make sure you are not logged into the manager while trying to upgrade]
When moving the site to the new server rather watch two things:
the right paths into this files
/config.core.php
/core/config/config.inc.php
/connectors/config.core.php
/manager/config.core.php
the folder /core/cache/ is empty. They can be cleaned simply by removing the contents via ftp.
and correct the value in the database back to {core_path}
I have magento installed in a subdirectory. www.domain.com/subdir/magento
This site worked perfectly at one point. I changed nothing, until my client said he couldn't login to magento admin.
I logged in just fine from my computer, but on his computer it just redirected back to the magento admin login without an error message and a url that looked goofy like this:
http://domain.com/subdir/magento/index.php/admin/index/index/key/3097210b826ac4a86d7531cb4089c9d0/
I thought that his cookies were being blocked, but that was not the case.
My magento settings were secure/unsecure baseurl: http://domain.com/subdir/magento/
web cookie path: (blank)
web cookie domain: (blank)
After clearing out var/cache, I found that I myself could not login to the admin either, with the same exact issue.
I tried the following settings without luck:
path: /
domain: domain.com
path: /subdir/magento
domain: vigrond.com
I also tried commenting out those lines in Varien.php, but that had no effect either.
My server account is a VPS and it has plenty of free space.
So I'm pretty much lost, wondering why this happened in the first place when it worked before (didn't change anything), and why it's so complicated?
Any help appreciated
If a login error message ("invalid password", etc.) isn't being displayed it's almost always a session cookie problem. In order to rule it our entirely, use Use your browser's cookie viewer and/or your favorite HTTP traffic sniffer and check
That all the cookies have proper expiration dates after being set
That the session cookie has a consistent token name/value for each request
That PHP, when running through Magento, has the various session lifetime ini settings at a reasonable value
That PHP can write to whatever it's using as a cookie storage medium
That the server's time matches the real time, and that PHP itself has a timezone set
Find app/code/core/Mage/Core/Model/Session/Abstract/Varien.php. in your Magento install folder. Comment out the lines (see below) 80 to 83. The line number may vary.
// set session cookie params
session_set_cookie_params(
$this->getCookie()->getLifetime(),
$this->getCookie()->getPath()//,
//dependes which versin of mage you are using, you may comment these as well
//$this->getCookie()->getDomain(),
//$this->getCookie()->isSecure(),
//$this->getCookie()->getHttponly()
);
This is caching issue. Which recently Magento community confirmed that is sorted but it is not. :)
Just clear your cache and do this steps it should work anyway.
Comment this lines also
// if (!$cookieParams['httponly']) {
// unset($cookieParams['httponly']);
// if (!$cookieParams['secure']) {
// unset($cookieParams['secure']);
// if (!$cookieParams['domain']) {
// unset($cookieParams['domain']);
// }
// }
// }
//
// if (isset($cookieParams['domain'])) {
// $cookieParams['domain'] = $cookie->getDomain();
// }
Make sure you have cookies enabled in your browser, try a number of
different browsers including Safari or Opera. Chrome will give some
problems and you need to remember to clear you cache in Chrome after
making changes!
Make sure you file permissions are set to EVERYONE - FULL CONTROL for Windows and 777 for your Mac/Linux environment If all that still doesn’t work you can try this: (I do not recommend this solution for a production version of Magento, but for you local test enviroment this will work.)
Check the version of php you are using. If you are using recent Magento try to find which version of PHP and extensions requires.
More details
Did you erase the session storage in var directory?
In my case, when I was playing with autorization for multistore on subdomains (changed path and domain for cookie as you did), this method helped me to drop the "bad" cookie and sucessfuly logined in admin:
In apppath/var/session directory I've made command in shell (be careful with path, this could delete all the files in the directory)
rm -rf /path/to/magento/var/session/*
And then just clean the cookie for domain in browser.
I was fighting with this issue today on my local server. I couldn't login using any browser. I really didn't want to comment out any lines in core files or doing any other "dirty" solutions.
Firstly I checked cookie set by browser. It had expiration set to 1970, so clearly it was a cookie problem.
I checked values for cookies in magento database. In phpmyadmin I found table core_config_data, then fields with values : web/cookie/cookie_domain and web/cookie/cookie_path. They were both blank.
My solution was to set:
web/cookie/cookie_domain to my domain name
and
web/cookie/cookie_path to /.
Example:
your domain where you run magento is magento.local
set:
web/cookie/cookie_domain = magento.local
and
web/cookie/cookie_path = /
I never resolved the issue. But I wiped the clients computer and reinstalled windows 7, and it worked. It was very strange that it didnt work before as he was not behind a proxy, did not have ad ons or viruses. And the issue reproduced in each of his browsers (chrome firefox and IE). It was not a router issue. It was a windows issue, but I couldn't tell you what exactly was causing it. It was not the internet security settings either, as I checked those. Also checked the host file. As I said before, very baffling
I had the same problem, but I was working on XAMPP on windows 7 x64.
In Magento system - configuration - web - session cookie management change Use HTTP Only to no and Cookie Lifetime to 86400.
I only changed the Cookie Lifetime just in case of daylight saving time may not have to be changed.
Before the changes I could only login using Firefox and after the changes all browsers work.
Leave Cookie Path and Cookie Domain blank.
Check the cookie configs in core_config_data table and check if your session is being saved on db. In my case, someone just changed the cookie domain and the cookie path with a wrong value.
You can also check this on the node in your app/etc/local.xml.
If it's on db, maybe you should change do files to be able to clean the session data directly on var/session dir.
Delete cookies (related to your domain) from your browser setting.
I was facing the same issue and at the end i found that it was due to full disk space and due to this Magento was not able to create sessions file in the var var/session folder. After cleaning up log files that issue was resolved.
Also, you can update the password in the database if everything else from above didn't work and you need desperate access:
UPDATE admin_user SET password=CONCAT(MD5('qXpassword'), ':qX') WHERE username=‘user’;
replace user and password words according to your needs.
If nothing works, make sure the disk quota is not exceeded. The new session cookies created under ./var/session will be zero bytes length if disk quota for the user is exceeded.
In Case, that you dont see any cookie named "frontend" or "adminhtml", when you reload the page, the Magento cookie wasn't set. In my case I have a wrong cookie_domain.
I used "null" instead of "NULL".
As I set my cookie_domain to NULL in core_config_data, the problem was solved
I am just beginning with Joomla on a linux fedora server (running apache,mysql,php), running in local. I have also installed phpmyadmin.
I have dowloaded/unizip joomla on var/www/html/joomla1 and created a database for joomla1.
Then restarted the server. Selinux is set to permissive.
However when browsing at http://localhost/joomla1/ i simply get a blank page
Any idea what's wrong ? How to fix this ?
Check your database permissions (does the user have permissions to access the data), check your error logs on the server.
Maybe this URL is right?
http://localhost/html/joomla1/
Check /var/log/httpd/error_log
Look for anything saying "Fatal:"
This will give you an indication of whats causing the problem
