I have had big problems today reaching the login page at https://secure.chess.com/login.html

I kept getting this message:
An error occurred while processing your request.
Reference #97.b528434d.1287043562.591fd9f 

Obviously I have managed to login now :-) so this is FYI in case
others are struggling. 

I had the exact same problem earlier today.

Occasionally when logging in is a problem I can get round it sooner  by Googling for chess.com log in... you then have to look carefully above the ever present  flashing adverts to see a rather inconspicuous " sign in" box ... it works !usually !

Yes I had the same problem for at least an hour, tried getting to the login page at least a dozen times.

I have just received an email from chess.com support and apparently this is now fixed (I had the same problem this morning). I am obviously now logged in so I am guessing the issue is indeed resolved... 

If it is still causing anyone issues it may be worth clicking the following link before trying again:
