I installed WP 3.0.4 on our server last week. I followed all of the setup directions for multisite, and it seemed to work fine. The only problem is that when I link to one of my child sites (our.network.com/blog1, our.network.com/blog2, etc) without using a trailing slash, it shows a redirect loop error. With a trailing slash, it's fine.
I tried adding code to the .htaccess to add a trailing slash to all URLs, but it made no difference.
I'd appreciate any advice on this. Thank you.
