Hey, guys. Our EE site continues to work fine, but we are having trouble getting into the Control Panel. We are not aware of anything having been changed, but for the past week the login page loads, we put a valid user & pw, hit Enter, wait a very long time, then get a 500 Internal Server error page. However, if we then return and put in a bad username & pw combination, it says “wrong login,” but we are then in fact logged into the control panel!
Looking at the log file, all of the attempts that appeared to time out were successful. This seems to happen on all browsers and via all ISP’s. Any idea what we should look for to make it work normally again?
