[Xiaoxiao]

I log into bitstamp ( i have 2 FA).  And this is what happens:



then i press back and it says 403 and its gone or something. 

then i press back again and it goes to my account and everything seems fine.

is this happening to anyone else?

CSRF is a one time token in the code that prevents other sites from hijacking your session.

This error probably occurred if you loaded the login screen, then waited for awhile (say 20 minutes) before submitting the login details, as the token would have already expired.  Could also occur if your IP changed between loading the login screen and submitting the login, or if you have a really intense caching settings in your browser which is loading an old CSRF token from cache.
