Is your site live? are you able to access the front end of website?

you need to check your server's error log.

if you actually see the login page and the error popups after login.

Hi Elino

Sounds like your store have been put into mainteance mode, it should however affect the entire store not just the admin. But if it is in maintenance mode, please check for a file in the webroot, called maintenance.flag. If you remove this your store should return to normal.

I hope this helps :-)

As @Theis Corfixen  said, check for the mainteance.flag file.

If that file isn't there maybe you'll need to check the var/report directory and look for any kind of report.

Please remove maintenance.flag file from the root of your magento folder or you can run magento-cleanup.php file from the root folder.
