Server-wide error pages

AFAIK unless each site will have it's own 404 error page. We put a generic 404.shtml in our skel folder so any new accounts will have it. We also have a script which will put the file in any accounts that are missing it, mainly to keep it out of the http error log.

I think you could just hand edit the httpd.conf and set Errordoc 404 http://www.hostname.com/404.htm or whatever. You need to look at some of the post for editing hte httpd.conf on cPanel 11
