404 Errors in WP Multisite

I'm setting up a Multisite network (setup for subfolders) and am running into a problem with several pages coming up as 404 errors.

An example page is located at:

Inside the admin, the page appears to be fine. Even shows up in the site map that displays on my 404 pages. I used the .htaccess code that was given to me by the install.

Also of note, I imported the pages from this site from another install. Not sure if something went wacky with the import, but even when I try to just create new pages, they don't show up.
