I'm pretty shaky in terms of my .htaccess knowledge, so I don't really know how to search for my problem. I can only explain whats happening. Maybe somebody could point me in the right direction?
Wordpress MU doesn't like it if there is a sub directory on the actual server with a name the same as the blog, even if there isn't a index.php file there. How can I fix this?
The problem is, is that I put MU on the server to replace individual wordpress blogs, they were all running in sub domains that have the same name as the blog that MU will use. This is because a lot of search engines have indexed the pages, and many other sites link here, and I want to preserve the directory structure. There is some stuff that can't be removed in the sub directories where the blogs were. Like I said, the root of these subdirectories have no index files in them, but just having the sub directory there is enough to cause 404 errors when you enter the url of the blog.
