Don’t directly link to the ‘raw’ version of the pastebin code, we can’t easily edit to show revisions.

If you look at bp-default theme sidebar.php you’ll see examples of how user links , avatars etc can be rendered;  you’re trying to run functions that are only populated from BP classes when on those component pages, so they will fail on normal WP pages.

This would get you the user name and link:

bp_core_get_userlink( bp_loggedin_user_id() )

@jstormthakid not sure I understand the question.

BP is installed and activated, therefore it is ‘added’ as it were, you can’t have all template tags / functions working on any old page things don’t work like that, on certain screens BP has created them thus knows what they are for and provides objects to them on a general page BP hasn’t any knowledge it exists so you need to use bp globals or functions as above that do work on any screen / page.
