 WORDPRESS 4.8.1
 BUDDYPRESS 291
 THEME WOFFICE

 I have updated WordPress today and Buddypress then this appeared:

 Warning: call_user_func_array() expects parameter 1 to be a valid
 callback, no array or string given in…wp-includes/class-wp-hook.php on
 line 298 appearing on the bottom of each page.

 I still get the notice when I upload older versions.

 How can I remove this warning?

 Thanks!
