Now, when I try to log on to update my site I receive the following error: Not Found The requested URL /wp-admin/upgrade.php was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. Apache Server at onlinetaco.com Port 80 Any ideas of what could’ve happened? I’m a school teacher w/o lessons for tomorrow since my site cannot be updated!! Help! Thank you all.
