I just bought the Membership (2.1.2) plugin, and wanted to use it on a site that's on WP 3.3 beta 4 (about to be released). The plugin is not ready for 3.3; when will there be an update?
It's the only plugin that doesn't play nice with 3.3; the display is so messed-up is has become unusable. Too hard to tell what is what, esp. in "access levels" - which is kinda what it's all about.
Also, when deleting members in WP, the plugin will remove them from "members", but still list (the total number) in 'subscription plans'? Not sure if that's a 3.3 issue?
