Still an issue here, this is Day 3 of entering email and password then being redirected back to the Log In page instead of FS loading up its Homepage!
However, my details have been accepted as I am now logged into the forums and can also access FS via the Account page on here, so it seems to be an issue on just the Log In/Create Account page itself?
This is in UK and on Android, no access to PC for the moment.
I had this problem yesterday too, i couldn't log in from my laptop but i could from my phone... and i did clear my cache and still got nothing. I did eventually get in after awhile, but like DC said you could type in your account info, hit login and it would just revert back to the FS main page.
