I started having trouble logging on last night - when I went to logon, I would get the login screen but after putting in my username and password and clicking OK, all I would get is a blank screen instead of the admin panel. It was still doing it this morning, so I decided to try resetting my password. Same problem; the admin panel won't load, I just get a blank white screen and url/wp-login.php
Anyone have any ideas? I am running 2.5.
