Urgent CRE Loaded Fix Needed.

Hi there. I am editing the pre-installed categories on CRE Loaded with my own ones, however it all works fine, except for when I enter or change any text in the HTML box for the category description. I get the following error on screen: Forbidden You don't have permission to access /admin/[login to view URL] on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. However, it all works fine when I just change the name of the category or image. I do not get the 404 error at any other time apart from when I edit an items or category description. I have also found this in the access logs that may help anyone who can help with the problem: /admin/[login to view URL];cID=&action=new_category_preview Http Code: 403 Date: Feb 06 21:52:12 Http Version: HTTP/1.1 Size in Bytes: - Referer: /admin/[login to view URL];cID=&action=insert_category If anyone can help me fix this I would be greatful. I have access to root in my directory, as it may also be a server issue. I would appreciate an experience programmer to try and fix this for me.
