BuddyPress.org

I have WP 5.2.1, BP 4.3.0, PHP 7.3.5, GhostPool Aardvark Theme 3.5

I can create groups, but when I click on the group, it never opens and I get a white page.

I have tried deactivating plugins, didn’t resolve issue.
In error logs I have this:

PHP Fatal error: Uncaught Error: Call to undefined function bp_nouveau_group_meta() in /home4/bandarro/public_html/wp-content/themes/aardvark/buddypress/groups/single/group-header.php:24
