Magento backend showing blank pages after login? - magento

I have magento 1.9 version and It is working fine on local and demo server but when I move this to live server its admin is not working.It just login admin and only header and navigation bar shows up there.
I tried with remove cache, sessions.disabled all newly installed extensions.but still same problem.My frontend is working fine.
Please help me to solve this issues.

This error was coming due to some entries in table "adminnotification_inbox" . I don't know why this happened.I just empty this table and my admin works fine but as soon as this table have entry same problem occurs, So After empty that table I disable admin notification from following location:-
System->Advanced->Disable Modules Output
Mage_AdminNotification
This solved my problem.

flush your magento root /var/cache folder and /var/session folders, It may have previous server session that may cause problems.

Magento /admin panel doesn't work

After I copied my magento installation on a new domain. The admin panel doesn't work. I checked the .htaccess, baseurls and tried a lot of other things, still the 404 error page.
The version of my installion is 1.9.
Please follow the following step.
delete cache folder from var
if you domain name changed then open your database and select core_config_data and set secure and insecure web url to your domain specific url
if you have still further problem for css and js and you have to make merge css and js flag to 0 which is also found in core_config_data
Thanks,
Sam
I hope sagar helped you to get rid of the problem.
to my opinion this issue happens due to improper setup of the core stores in magento.
what I did to resolve the issue to check the core_store tables. Check if store admin is active.
Make it active and your 404 problem will go away.
Thanks me later !!!

Magento admin page blank after login

My magento version 1.8.0.1 website admin panel shows a BLANK Page after login in. until 2-3 days ago its worked perfectly; I made no changes in any file related to my website.
Could anybody tell me that what's going on with my website & what is the cause of this problem.
An image of the blank page: http://i.stack.imgur.com/pmskn.png
Flush your magento root /var/cache folder and /var/session folders, It may have previous server session that may cause problems.
To rectify this problem:
Login to database via phpmyadmin or any other mysql client.
Open core_config_data table.
Find entry with path like dev/log/active.
Set its value to 1.
Delete /var/session and /var/cache folders in your installation.
Retry to login to admin panel.
If problem is related to functionality, there will be log files in /var/log folder.
You can trace cause of problem from log files of magento.
Please let me know if you find any difficulty.

Magento Customer Login Issue - Login Page Keeps Reloading On Login

So I found several variations of this issue and tried the solutions; none worked.
So customers are not able to login with the correct username and password. The login screen (https://www.example.com/customer/account/login) just refreshes when the credentials are entered correctly -- should redirect to the My Account Dashboard.
The only thing that seems to temporarily work (few hours at a time before the problem comes back) is when we change back and forth the System > Config > Web > Session Cookie Management > Cookie Domain to "https://www.example.com" and ".example.com" Then we flush the Magento Cache and we flush the Storage Cache and refresh the all Cache Types.
After this, Customers can login on Firefox, Safari and IE, but not Chrome (same login page looping issue).
We have exhausted everything we can think of. No errors in the logs and we have the correct getBlockHtml('formkey'); ?> code in the login.phtml files. We are using a custom theme and noticed this problem after migrating the site from Enterprise Edition to Community edition.
Any suggestions would be greatly appreciated!
Thanks for reading this article and opportunity to post my answer here.
I also faced same problem which AShah faced. I also googleing but did not find such proper result. Finally I removed or clean the session folder (root>var>session) and its works fine for my store.
Hope this trick will solve you. thanks
First check what are the values set for following path in core_config_data
table
web/cookie/cookie_path
web/cookie/cookie_domain
Try by replacing any existing value by NULL.
Following should be set to 1
web/cookie/cookie_httponly

Error empty response when logging in magento admin

I really stuck on this issue, everytime i log in into magento admin, it's give me an ERR_EMPTY_RESPONSE on google chrome and Connection reset on Mozilla.
The shop is still accessable, but it's load very slowly. It's working fine before, and suddenly become like this.
I can't find a similiar issue like this, mostly are the shop that return an empty response and they still can access the admin page and it's caused of enabling flat category/products set up.
I'm not sure if client enabling the flat category/products. If it so, what table should i edit using phpmyadmin?
since i can't access the admin page, or there are another thing that cause this? some error code, some files missing in admin directory or htaccess thing, actually i'm not doing changes on htaccess before. Really need your help.
Restarting apache and mysql worked for me
service httpd restart
service mysqld restart
Hope this helps.

Magento Admin login kicks me out back to the Admin login

After I enter my username and password and click "Login" it sends me back to the Login page with NO error messages. The URL changes to include a session key and that's it. Everytime I click Login again, the session key is regenerated and I still can't log into the admin interface.
I just encountered this problem on one of my servers (not a localhost installation). Turns out the system account was over quota, so I presume Magento was unable to create the necessary temporary files. (I noticed this when trying to create a directory on the server over ssh.)
So... maybe check to make sure the account under which Magento is running isn't over quota on your server? At the very least, it might not be a Magento problem directly.
Clear the contents of the directory var/cache and try again.
If that doesn't help check the table core_config_data in the database for records with a path value of "web/secure/base_url", "web/unsecure/base_url" and "admin/url/custom". These should match the page you are trying to log into (but without "index.php/admin/" at the end)
Finally check your browser's cookie settings and that the server's PHP is able to set cookies.
I was having the same problem running Magento 1.5.1 on my production server. I would log in to the admin, the url would show the address for the dashboard (with the secure key), but the screen would still be the login screen. There was no error. This happened with FF, Safari, and Chrome.
I fixed it by manually setting two core_config_data values in the database. They are as follows:
web/cookie/cookie_path = /
web/cookie/cookie_domain = "mydomain.com"
clear out var/cache and try to log in. For me, it worked.
Version 1.7.0.2 I have been moving my magento store from on server to another one, and I had the same problem. Use phpamdin to edit your database on new server, search for web/cookie/cookie_domain in 'config path row', the value is probably your old domain name: yourdomain.com, change that to your new domain name OR to your new IP address (new server). If you attend to use your old domain on new server environment you will probably want to set your story ready before you switch your name servers. That was the case for me, after I added my new server IP to web/cookie/cookie_domain instead of domain I was finally able to log into my magento backend.
I had some problems when on a local server. It was on http://server/username/ and so didn't have dots in it. If we changed the settings to be the IP address of the server then it was fine.
There can be several things that cause this behavior. This is my checklist. One of them will eventually fix it.
Click the "forgot password link" and then the "back" link. This will remove any possibly misplaced params in the URL as well as make sure you're on the right server (some installations have separate admin servers)
Clear cookies or use an incognito window
Try another browser
Local installations: Try using 127.0.0.1 instead of localhost (and update the base URL in the core_config_data table)
Clear Magento cache, full_page_cache, and session directories in the magento/var/ directory (and repeat 1 and 2)
Truncate the core_session table
Verify your Magento has correct memory settings
Check Magento system.log and exception.log files and debug
Check PHP's error logs and debug
I've experienced this issue using Opera, while in other browsers it worked fine.
Also, make sure to set correct cookie options in:
System > Configuration > Web > Cookie Settings
Also, make sure that your system time / time zone on the server and php and magento match up.
