I’m assuming you meant to edit the functions.php file in my parent theme directory, not the child theme (where the functions.php file only has the enqueue style coding). Or should I just be adding your suggested code to the child theme’s functions.php? (… in which case it would not be line 300-something.)
So I edited the parent theme’s functions.php as you suggested, and uploaded buddypress.php to the main theme’s page-templates folder.
It didn’t work on the live site, and it also it did not show in the WP “preview” of the parent theme. I’m reluctant to switch to the parent theme since it would wipe out other more important customizations.
Thanks for any advice you can offer.
