I recently installed and configured the New Blog Templates on my multisite. After selecting the advanced tab and all the extra tables, my entire multisite crashed.
I had to use my host backup to get my network back. I even tried to use a Snapshots backup I had made, but that didn’t get back my user sites (that’s a different issue).
I love the idea of this plugin to create templates, but I’m afraid to use it now. Have you had any other reports of problems with this plugin?
