Members can't log in

Hello,

Currently running 4.1.1

For 2 days now, no members or admins can login from the front end (pretty big deal of course). Admins are able to log in from the back end.

I’ve removed the Login with Ajax plug-in and reinstalled it with no success. Upon attempting to log in it takes the username and password but then the spinning graphic comes up and just hangs there indefinitely.

I’ve tried using the bbpress login widget and it accepts the username and password but just takes you back to the homepage (not logged in).

I’ve cleared cookies and cache, I’ve tried safari, chrome, and firefox.

This is a very big problem for my site and users, can anyone please offer some assistance?
