It is a common issue with vBulletin. If you get 404 – page not found error in vBulletin, first try enabling RewriteBase within .htaccess file.
In order to do so please find the following line within your .htaccess
and uncomment that line.
If you have installed vBulletin inside a sub folder such as forum you should use the following RewriteBase
RewriteBase /forum/
If this does not resolve your problem please make sure your host supports mod_rewrite and you are allowed to use .htaccess file on your hosting.
