Cant post in BTS? Privliges taken away?

I just tried to start a thread in BTS and was not able to. At the top of the screen it said that my posting privliges have been removed I have never posted in BTS, and I wanted to spend a little more time there. Can someone help please

Have you logged on to BTS?

You use the same password as for ATS.

Yes, Im using my login and password from ATS. i dont know whats going on, since I can post here.

Try logging out, then back in. The two domains share the same database, so it's not possible for a user to be banned from only one of the boards.

Ok, I logged out of ATS, clicked on the BTS tab, logged in, went to the Computer help forum, and the login and password appeard at the top empty, and a red message to the right said "you are not logged in, or registered at ATS." I can log into the Forums list page of BTS, but when I click on a forum, my log in cancels out.

You need to clear your cookies. Have you had a previous ATS username that was post-banned? If so, it sounds like the BTS cookie is based on that other username, not this current username you're using here. (And you don't need to log out of ATS)

Ive never been banned. Been warned a time or two Ill try clearing my cookies and see if that helps. Thanks SO
