I recently downloaded the security fixes from here:
I uploaded these to my blog with an FTP client... and the WordPress admin dashboard promptly stopped working.
In sheer desperation I replaced the files with the original 2.5 files... nothing seems to help. The blog itself seems to operate fine, but I can't access any of the WordPress administration settings.
Any help would be greatly appreciated.
I recently started the blog from scratch... and, honestly, if I have to do that again, I may cry. lol
