I just created a multisite. I am testing the tools you have to copy courses to all the multisites I have in one push. I am using the Multisite Content Copier. The copy looks like it finishes up alright and I can confirm there are new entries in the database for the course, but when I try to navigate anywhere after the copy none of my multisites work. It brings down my entire network. I have to go through FTP and remove coursepress for anything to start loading again, and after that I am unable to get coursepress to activate again. It looks to be getting caught in some kind of infinite loop.
I only have the coursepress, multisite content copier and wpmu dev plugins active on the default wordpress theme.
