Did you remove the facebook link and other scripting? My thoughts are that could be what is causing your javascript error and impacting the plugins. That said we can't really claim it doesn't work with any of our themes when you say you've tried one or at least only told me one. I also do not see why the theme would impact a plugin url. It again is something likely to be in set up or an error causing issues.
As we do not have access to the plugin I went to your site to try and see again but I see you are not actually using the theme or even default but a modified one?

The problem is Studio just like all our themes uses the same hooks or 'things BuddyPress looks for' as any theme. It also does no redirects or anything fancy like that. I'm therefore puzzled why a link I see in source will be created as a # which is what you are getting. My thoughts do turn to if an error is occuring. We can test this though.
1. In buddypress-navigation.php (library/components/buddypress) just add a link that exists at this point:
<?php do_action( 'bp_nav_items' ); ?>
Make sure it's a proper navigation link to a real place. Then we can see if adding a link in that 'hook' which it seems the plugin uses will have issues or not. If it does not then we know the theme isn't causing redirection.
I would like to clarify we do not ever get into debates about themes or plugins that are other people's we do our best to adhere to the Default standard theme (not variations) and use that as our gauge. However we do use JavaScript in some themes and scripting default does not. We do as I think you are seeing do our best to investigate but we can't know all plugins particularly premium ones exclusive only to buying them.
