I tried to log into a blog I administer, after 2+ weeks of no issues, and today I suddenly cannot log in. I have not updated the core or any plugins. The DB hasn't changed, and no significant changes have been made to my system.
I've tried IE, Firefox, Chrome, Safari and Opera, clearing cookies before each, in normal and private browsing modes. I've tried renaming my plugins folder and my theme folder. It's not a password issue. The login page just reloads over and over, and it just started happening out of the blue.
I've run into many posts about this, and disabling plugins or changing settings on config.php seem to be the most common solutions. But none of these have worked for me! Any new suggestions?
Update It looks like it's upgraded to 3.5.2 (from 3.5.1) and that may be causing the issues, though I somehow doubt such a small update would cause such a big fuss. Since no one updated it, this leads me to also ask...does WP auto update?
