Since I updated to 3.3.1, I have lost administrative access to a host of my sites, some of which I maintain for others. I've tried disabling all plugins, to no effect. I've tried reinstalling the WP files, to no effect.
No longer do my un/pw's work. When I enter the URL for wp-admin, I get the site home page instead. In some cases, where I've been able to get a new pw that works with wp-login.php, I get the admin toolbar, but no dashboard. There's the home page instead.
Some of these are very old sites, so I can't just trash everything and start over.
I'm thinking an older version of WP might be the answer... other than shooting myself to avoid the humiliation of telling people their sites can no longer be updated.
Where do I get an older version?
