umm, Now I’m a bit confused.
The filter only affects the bbp breadcrumb, so that fact that your theme doesn’t have breadcrumbs is irrelevant.
If you just add that code to your themes functions, it will be used by bbPress as it loads and not display.
I presume that’s where you put the previous code to change to blogs? If not try that code again!
Whilst you can add it to a default theme such as twenty eleven, keep a note of it, as any theme upgrade will overwrite it. you should consider a child theme to let you make changes without affecting the core code and themes see https://codex.bbpress.org/step-by-step-guide-to-setting-up-a-bbpress-forum-part-2/ for some info on child themes
