A little further poking around and it seems to be happening every time I link to something from the main page.
Login bug

Same here WW. I've had that problem for a while now. Maybe that's a sign they are going to do some sorta maintenance soon?

I am running Firefox 4 on Windows 7 and I have a bug when I type in my username and password at chess.com it redirects me to the main login page and says "You do not have permission to access this page". It sometimes happens, it sometimes doesn't. It is getting slightly annoying today. Could you please fix that? Thanks.
Today I've noticed that the site has been logging me out occasionally as I navigate between pages, particularly I can reproduce it every time I go to my online chess page under "Play" and "Online Chess" in the dropdown, at least from the main page. I think it also happened when I clicked on the Game of the Day link from the main page. I'm running Firefox 6.0 on Windows 7, and I've never noticed this problem before today, and I use the site all the time. Is there something that's changed recently in the site that could have changed that's affecting this?
