Out of no where, today I tried logging in through firefox and IE to the plesk control panel. After I enter the information, I'll be sent to a blank screen with only the plesk logo up top. If I deliberately enter wrong information and press log in, it'll give me a pop up saying log in was incorrect.

What could possibly be wrong?

 

I think I know what's wrong.. the plesk updater crashed a few days before while updating.. now it's broken.. going to reinstall everything to fix .
