Hi Kelly – i’m currently testing this plugin, ver 1.3.55, on MultiSite 3.3.1 and it seems to work … e.g., i activated it on a sub-site and not on the other sub-sites and indeed the plugin groups / roles do not transfer from one sub-site to the other … initially i thought i experienced the plugin showing groups / roles on the primary site but i believe this was browser cache thing as i had several windows open during testing and then cleared all cache and now have not been able to repeat …
i am having issue protecting direct file access and my notes from testing previous ver 1.3.27 indicated that this htaccess trick worked but not yet in 1.3.55 but here again, i might be missing something ..??..
