I updated to 1.7.0 with no problems until it forced me to update plugins manually in the admin area. After I updated my third plugin (birthdays), the site seemed to crash and no longer loads. I get the following error: 

Not Found

The requested URL /e500.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.

Anyone had this issue and no how to fix it? I cannot even access admin panel anymore. Everything 404s on me. I checked the file manager and database and everything is there. It's just really weird.
