Magento admin page blank after login - magento

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.

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.

Unable to login into magento admin

"Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime
or capacity problems. Please try again later."
if i give any url of my magento site I am getting the above output. How do I resolve this? Please Help
You probably have a file named maintenance.flag at the root folder of your Magento. This file is there to provide people to access a given magento when you are doing maintenance on it.
Try removing this file from your magento root folder.

Magento Admin Panel URL change not taking effect.

I am attempting to update the admin panel url.
I edited app/etc/local.xml and changed the following line to the desired name:
<frontName><![CDATA[admin]]></frontName>
I then went to my Magento root and cleared the cache by running rm -rf var/cache/*
This exact process worked beautifully when I first tested on my remote staging server, it updated to the new URL immediately. However, there was absolutely no change when I attempted it on my live site. The admin panel still showed up when I visited www.mysite.com/admin.
I had a short window of time when the traffic to our website is low and nobody is actively using the admin panel, so I changed the name back to admin and cleared the cache again after my change did not take effect.
Any ideas what might have gone wrong?

I personally used step 3
another way is to change from the admin itself.Goto System→Config→Admin→Admin Base Url→Use Custom Admin Path, set yes. Set new admin path in Custom admin path text field and save.

Magento site restoration

I have a situation where I had to restore my magento site from an FTP backup which I made earlier of all the files and folders of the public_html directory. Note that I don't have a mySql backup.
Now when I try to visit my www.domainname.com site, it just displays an error number. Note that I can no longer go to www.domainname.com/admin. I do not know how to enable debug logging so I can see what the error number is trying to tell me. However, I can go to my hostgator.com control panel and click on the error logs, but there are no entries.
My question is: is there any way I can salvage the original site, minus the database? I'm okay with having to re-enter products, etc., that I once had into the database.
Thanks in advance.
The site is 85% the database. No database backup, no site.
You must backup both your public_html files and your Magento database to fully back up your Magento e-commerce installation.
Basically all you have is the application, code changes, skin and templates from the previous version.
Configuration, CMS pages, categories, product and all the rest live in the database.
The error number displayed is the file name of a stack trace that ends up in var/report. It's probably telling you that no database exists at this point.

Magento Admin 404 after sessions expire

We have just moved our joomla/magento site to a new server. We are now getting some intermittant 404 errors for the magento admin panel
We are able to use the Magento Admin periodically. After a couple of hours we will start getting a 404 after logging in. Once we manually clear the magento cache it starts to work again.
When we start getting the 404 the issue appears to be related to the URL.
Our setup is:
Joomla is in the root directory.
Magento (1.5.0.1) is in a sub-directory /magento
When the Admin panel (www.oursite.com.au/magento/_admin) is working the url after login is
https://www.oursite.com.au/magneto/index.php/_admin/..........
When the 404 starts occuring the url drops the 'magento' out of the url and becomes
https://www.oursite.com.au/index.php/_admin/............
After manually cleaning the magneto cache the issue is resolved. After a few hours it starts to occur again.
Any help would be appreciated.
Well I found the solution to the problem that we have been having.
Some where along the line the permissions of the magento/var/cache directory where incorrect. Apparently if magento can't write to this directory it starts writing to the global /tmp directory.
This post on the magento forum has the info and solution:

Hope it helps someone.
