Your Forum Real Link Is
http://animefrantic.com/
But When Any One Login Then Your URL Is This
http://www.animefrantic.com/fourmsvb/index.php
This is Problem
If You Want To Use Simple This Link
http://www.animefrantic.com/ Then
Goto admincp - > vBulletin Options -> Site Name / URL / Contect Details Then Add This Link In Homepage URL and Forum URL
http://www.animefrantic.com.index.php
If You Want To Use This
http://www.animefrantic.com/fourmsvb/index.php Address Then
in Your ftp in Public_html Creat New directory Name "forumsvb"
And Then Move All Files In forumsvb Folder.
I Hope Both Tips Usefull For You.
