I am getting this error:

Fatal error: Call to undefined function bb_get_id_from_slug in home/u123456789/public_html_wp-contents/plugins/buddypress/bp-forums/bp-forums-functions.php on line 264

Please help me guys. What’s wrong with the installation? I am getting that error whenever I create a forum/topic on a group. Then, when the group is refresh/back the forum/topic title is already their. And I also get that error when I open/clicked the said topic.

For some reason, you’re using the retired version of BuddyPress’s forums, which is only used for legacy installations from over 3 years ago.

Deactivate the Forums component in BuddyPress.

Thanks a lot @johnjamesjacoby! I deactivated the Legacy Forum in BuddyPress and it worked! 😀
