I have upgraded my magento to 1.9.2 and had 404 on Home page and white screen (blank page) on /admin. Home page I have fixed, but i have no idea what is the trouble with admin page.

I have cleared cache, checked logs... Nothing special. Who can help please?

  • check php logs, something is broken. 404 maybe your store code lost, or htaccess and rewrites not working – MagenX Dec 24 '15 at 15:16
  • I already fixed 404 error. Now I try to understand why there is white page on /admin – MageLover Dec 24 '15 at 15:27

First enable Developer mode in your .htaccess file, add the following at the end of the file:


Next edit index.php and uncomment the line:

#ini_set('display_errors', 1);

Line referenced:

Ensure var/ is writeable by the webserver.

Enabling developer mode and display of errors you should now see the exception/error when attempting to login to the admin page vs a blank screen.

  • Try re uploading all files located in app/design/adminhtml/default/default/layout/ from a downloaded copy of the same version you installed via downloader (1.9.2.x) from magentocommerce.com – B00MER Dec 24 '15 at 16:30
  • I must do it manually or I can go to downloader and reinstall "Mage_Core_Adminhtml"? – MageLover Dec 24 '15 at 16:48
