I moved Domain name on my XF and moved the mysql database as well.
So I zipped my entire forum folder from the ftp server and moved it to the new server, same with the mysql database.
I updated the config.php folder with the new mysql informations.
I went into the admin panel, and updated the new domain name.
As I am using fusion style, i got a portal page, and when I click on forum, i get a new url www.website.com/forum/forums
it adds an extra "forums"
