I have MultiPress set up on my server with one sub-site. I installed a custom theme for the sub-site and most of it worked fine except a few things: 1.) The Blogger import gave me some errors. 2.) When I installed some other 3rd party plug in (for facebook feeds), it said it was installed but doesn't show in my plug ins list. 3.) The theme on the sub site would create pages in the back end, but when I went to view them, it gave me 404 errors. (I disabled JetPack and it got better, but it still happens. Can someone check my site via support access (enabled) and see if there is something basic that I'm doing wrong?
