Poe, please tell me what you did! I’ve just been struggling with the exact same problem as Ronnie TRFC. I tried to upgrade to 2.5.1 using the Automatic Update plugin, and it didn’t seem to work. It prevented me from getting to my login, so I deleted the WPAU plugin folder by FTP, then manually updated the WP files (as I have usually done). The site is updated, and it works, but I still can’t login. I tried adding index.php to the login address like: https://mydomain.ca/wp-admin/index.php and it worked! The question is how do I fix the problem properly?
