vBullettin 404 error

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

#RewriteBase /

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.
