 * I have recently started getting this error on all of my forum posts:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘
   publish_topics’ not found or invalid function name in …/wp-includes/class-wp-
   hook.php on line 287
 * Am using WordPress 5.4.1, Buddypress 6.0.0, bbPress 2.6.5, and PHP 7.1.33 .
 * At first I thought it had to do with the most recent updates to bbPress, but 
   after checking on the bbPress support forum, I tried deactivating the **bbPress
   Do Shortcodes** plugin and the error went away. If I try activating the error
   comes back. Could you look into this?
