I have set up WPMU and 3.0 network sites fine in the past, but this situation has me a bit puzzled.
Originally wanted to set it up as subdomains, but that wasn't possible, as I don't have access to cpanel or other admin privileges, so opted for subdirectories.
Main site works fine.
.htaccess file in place (correct base directory is set)
When I create a test user and test site, I try to view the test user's site and get a 404 error.
I've double-checked config files and .htaccess file according to what is in the network setup page.
Where else should I be looking for an error? What else could be wrong?
Thanks in advance!
