I think in my case it might be theme-related. I’m using Suffusion with Suffusion BP Pack plugin, and I saw on their forum that he’d used BP 1.5beta files. He claims an upgrade is on the way. In the meantime, I disable ‘Friends’ and am adding everyone to every group using BP Group Management plugin until the upgrade comes out. It’s half a solution, but better than redesigning from scratch.
I’m having a similar problem. I’m running BP 1.6 on WP 3.4.1 network.
I can write new PMs to any member and it all works great, but when I hit ‘Send Reply’ button the text box empties itself out and the reply is never actually sent as a message.
I used Firebug and discovered that the POST data is all there, but the AJAX/jQuery isn’t doing it’s job. Here’s why I see in the Firebug console:
which is supposed to be handled by `http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js?ver=3.4.1`
Moreover, I just noticed that the jQuery ‘Friend’ buttons aren’t working, either… URG! I’ve been disabling plugins like a madman but so far nada. HELP!
