First I had the bad gateway-error - couldn't access the forum.

I deleted cookies -- now I'm unable to login to the forum.

I'm stuck in a circle. I can visit my profile, then I click "Forum"  -- there I have to login, but I cannot open the forum site.

Same here I have to revert back to Internet Explorer

I have deleted all cookies and the history. This was the solution.  But it will happen again.

Me too!! l can't post, and my avatar's gone on Chrome. lt's useless. Same thing on Safari, l can't post or log in properly.

l can sign in here on lnternet Explorer but l don't like using it.

I can't login on chrome either.
