I recently tried to log in, but I unchecked the "Remember Me" box. This prompted an error saying something to the effect of "not all form fields are filled, please try again." (Logging in works, however, if you do check that box.)

 

Instead of hitting the enter button after you write the stuff out, try clicking the log in button.

I remember having a problem like that once on a different site.

I think it was the CN forums, but yeah.

Weird shit.

Just try it though.

 

I just tried it, and I had the same problem. It looks like it doesn't matter whether you hit enter or actually click "submit."

 

Confirmed. I get this problem as well on the current site and the development one. It looks to be server-side, but should be easy to fix when Raven has the time.
