MyBB Community Forums

hi all;
i've changed my forum url:
before was: www.mysite.mantainer.org
and now is www.mysite.com
i've copied the database and the files from the old site to the new site and after i've changed the path and the cookie into the admin cp but now the forum don't load the theme and login/logout don't work?
what's wrong?
thanks.

any helps?

Please post the link to your forum.

well i've reinstalled all........
the forum was and is ''virgin''; no member and no topic are in it.
I'll edit again the footer and the header and reinstall the plugin and the forum/sub-forum.
thanks however.
