Urgent Help Please

My forum was working today has been for months since installing VBSEO

Today i tried to setup

PHP EBAY PRO API which lets you display ebay in php

Anyway i had to add something to the .htaccess and I think in doing so It has messed up my forum

anyway i removed what i added and still this is the result

In doing so i think that may have effected VBSEO and now when you click on a forum, thread or a post it goes to my 404 page when VBSEO is on.. when its off my forum works

Please help

Just a quick update


When I turn off VBSEO.. my forum begins to work again i.e people can view posts etc.

When I activate it.. and check all my forum and posts etc go to 404 pages


Any ideas what i need to do to get it back to working with vbseo?

Ok let me back up

Have had vbseo working for months now perfect

Today something messed up and the forum topics, posts and threads just went to a 404 page

So i went into admin of vbseo and turned off , using the radio button for activate

went back to forum.. NOW i can access BUT now all my urls are back to the old vbulletin

If i go into admin again and activate it goes back to 404 page

How can i please get this workign again????

what do i need to do

all fixed.. i uploaded my old .htaccess over and that fixed it
