I run a Wordpress mulitisite system on a dedicated GoDaddy server. Yesterday I ran a Wordpress update from 3.5.1 to 3.5.2 and now if I try to login to any of my sites, I get a 404 page.
I've tried replacing the wp-admin folder, renaming the plugins folder, replacing the wp-login.php file, and deleting the .htaccess file. I checked the file permissions on wp-admin and the wp-login.php. Those are OK too.
I also checked the file permissions on wp-admin and the wp-login.php. Those are OK too.
I also ran the sitecheck.sucuri.net and my site is "Verified Clean".
Oh, and I also verified the domain in the database using PhpMyAdmin to look up the "wp_options" "siteurl".
And I verified that the "db_version" was "22442". :(
