I've got WordPress MU 3.3.1 up and running. The site is avalancheindustries.com. I'm not sure when this started happening as I don't use multisites that much right now and I have left my static pages alone for months.
If you check out the main site, it looks fine, but all the pages except the blog redirect me to the home page. I de-activated all plugins and reverted to the default theme and I was still having the same problem.
Also, if you go to another site, it throws all kinds of stuff out. Go to avalancheindustries.com/test and it looks like a blank theme. When I click on it's dashboard inside the network admin, it takes me to a cannot be found page.
I'm not sure if these two things are related or not, but any and all help will be welcome indeed.
