Re: Random errors disclosed when i added Invite Friends Plugin
First off, if you suspect or actually know that a given plugin is causing issues, you should contact the plugin developer and ask them. They may be aware of the issue and already have a new version in the works, or they may not be aware of any issues and thankful for the report.
Second, concerning an official listing of BuddyPress plugins, you can either find them here or search the WordPress plugin repository for the tag word “BuddyPress”. On the repository page for a given plugin, it will tell you on which versions of WPMU and BuddyPress the plugin has been tested.
Finally, as far as a listing of plugin conflicts, I do not know of any. You can search the forums here and find various threads indicating potential conflicts. But, since all the plugins are developed by 3rd-party sources, it is up to the users to figure such things out–with the help of forums such as this, of course!
