@dacai – It sounds like these shortcodes rely on javascript to work.

There maybe a conflict between your plugin’s javascript, BuddyPress’ javascript and/or your theme’s javascript (assuming you are not using a variant of the bp-default theme).

I would try to find out the culprit by debugging the javascript with your browser’s developer tool.

If you’re using Firefox, try installing Firebug.

Here’s a video tutorial on how to use Firebug:

Once you have it installed, turn on the Firebug console and reload your page. If there are errors, the Firebug console will tell you which javascript files are failing.
