Yes.

inc/config.php

But that can't be the case. I was just telling you to change the PIN.

But Im confused about your problem. Since you had some errors I think it's better try re-uploading the script and see if it fix the problem. It won't be fixed if it something to do with DB though. See if you forum members can login and logout without a problem. If they can then problem might be in your PC>

Well..
i've already do that
i re-upload script 5 times..
but i'll tell you the problem
my members can login/log out wirhout problems if i let the old edit(without changing Domain Cookie..)
but after i change domain Cookie.. no one can login/logout.. expect ACP..
if i send you forum detalis(mysql ftp detalis etc)
can you fix it ?
