404 not found when deleting threads..

[lsti]

Hello, i am using custom rewrite url's provided by vBulletin.

My forums are located in the forums directory.

So, when ever i delete (physically remove) a thread, it results in 404 not found. Other than that the rules work fine.

This is my actual url..

www.myurl.com/forums/forums/56-General

When i delete a therad from this section, i am taken to

www.myurl.com/forums/56-General

Which results in a 404 not found, guess the default ones have some issues if the url is in the forums folder.

RewriteEngine on

RewriteRule ^(.*)$ - [R=404,L]

Any help would be appreciated.
