yes, just the home theme is affected to my knowledge. I got the 404 to work when clicking a hard link inthe site that was not real, but if I type in an arbitrary page that was never created then I get the search page. I am using the default theme from the last version of WPMU, but slightly modified. I guess I will copy those functions and see what happens. thanks.
The only problem with doing it this way is that it may be lost during an upgrade, but I do not know how to create plugins, so I could not go that route.
i am using a different theme for the main theme. my 404 page is in that theme. It worked fine before upgrading to the latest versions of MU and BP. Were there some changes that may be causing the issue?
Thanks for the reply. I removed the file, and I can now get the home page to come up, but the wp-admin access is not happening. I get a blank white page that is forever looping. Any thoughts?
