After updating the plugin to the latest version, the Groups page does not show properly (groups do no display) and a Group Page is not showing up at all. Instead, a message displays:
Fatal error: Call to undefined function bp_get_groups_root_slug() in /home/websitefolder/public_html/wp-content/plugins/bp-group-hierarchy/bp-group-hierarchy-filters.php on line 152
Can you please help with what can it be?
Is it possible to get it working in my version of BP (1.2.9)?
(I have not updated BP yet because I expect a lot of things will need a fix after that..)
