If anyone out there is experiencing the WordPress white screen of death i.e. when you go to your wordpress wp-admin folder all you see is a blank screen, you may have been hacked.
I had a nasty little hack where link code was being injected into the footer of every rendered page. It was difficult to find as the links that were being injected were injected by an encoded script that had infected several files (especially in my themes folder). I went through each file and deleted the script from them. In this case, if you’re not experienced with code you would be safer to do a full re-install of your blog.
The result of the clean up was that several files had spaces injected into them at the top and bottom of the page. I did a full re-install to restore all the important files in the system and I still was experiencing the blank screen. Obviously wp-config.php wasn’t part of the update and so I cleaned out a blank line on the top of this module and I could finally log back in again.
Hope this helps someone out there.
Note: If you have been hacked, change all of your passwords, database, ftp, wordpress etc. and make sure that all file permissions on your server are set up correctly, be pessimistic.
