Thanks again Conor for your time

The file
YOUR-admin/includes/extra_datafiles/ceon_uri_mapping_filenames.php

Is there and I have checked all of the files a few times now but I'll go through it again just incase..

I have added this to the htaccess

Code:
# Don't rewrite admin directory
RewriteCond %{REQUEST_URI} !^/adminname [NC]
replacing adminname with my admin folder name.

Would this be all I need to add?

I already had this in my htaccess file

Code:
Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^ampmgraphics.com [nc]
rewriterule ^(.*)$ http://www.ampmgraphics.com/$1 [r=301,nc]
ErrorDocument 404 /index.php?main_page=page_not_found 
DiRectoryindex index.php default.php index.shtml index.html index.htm /index.php
AddHandler server-parsed .shtml
AddHandler server-parsed .html
AddHandler server-parsed .htm
I'll go through the whole process again and see what I've missed..

Thanks again...
