Uncaught Error: Call to undefined function BP_Better_Messages_Tab() Uncaught Error: Call to undefined function BP_Better_Messages_Hooks()

They probably refactored with version 2.0.0 and no longer use those functions.

Most of that plugin's userbase is still on 1.9 or earlier, so we'd want to do function exists checks before removing outright, and add in newer method to hide as well.
