WordPress 3.0.1 Multisite. Subdomains.
Right now, I'm just using the tags site to collect them. I have plans for using switch to blog, but I'm not there yet. Point is that it's a 'silent' install ;)
When I make a new post in ipstenu.org, for some reason I got redirected to http://tags.ipstenu.org/wp-admin/post.php?post=1245&action=edit&message=6 instead of http://ipstenu.org/wp-admin/post.php?post=1245&action=edit&message=6
When I removed tags from the URL, it loaded and everything was fine. If I don't, the post doesn't... post.
I'm not even sure where I should start looking for this one.
