MyBB Community Forums

I've recently set up a new site with a new domain, and I'm in the process of transferring everything to the new website. I've copied all of the files and the database, and I've updated config.php with the new MySQL details, but I can't access the forum. I can access the Admin CP (after editing the settings.php file with the new cookie settings), but none of the other forum pages will load.

Contact your host.

Is it possible that there's something I haven't done in order to make it work? Are there any other places (other configuration files, database entries, etc.) that rely on an address that no longer exists?

Edit: just noticed that syndication.php does return an RSS feed (although it has an extra line at the top and seems to be invalid). Also, sending relevant data to member.php from external pages does allow me to login and out.
