I get this error over and over and over and it quickly fills up the error log.

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘WHERE group_id IN (1) AND is_confirmed = 1 AND (is_admin = 0 AND is_mod = 0 A…’ at line 1 for query SELECT user_id FROM WHERE group_id IN (1) AND is_confirmed = 1 AND (is_admin = 0 AND is_mod = 0 AND is_banned = 0) ORDER BY date_modified DESC made by require_once(‘wp-load.php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’), do_action(‘init’), WP_Hook->do_action, WP_Hook->apply_filters, bbp_init, do_action(‘bbp_init’), WP_Hook->do_action, WP_Hook->apply_filters, bbp_register, do_action(‘bbp_register’), WP_Hook->do_action, WP_Hook->apply_filters, bbp_register_post_types, do_action(‘bbp_register_post_types’), WP_Hook->do_action, WP_Hook->apply_filters, bbPress::register_post_types, current_user_can, user_can, WP_User->has_cap, apply_filters(‘user_has_cap’), WP_Hook->apply_filters, Zqe\Genealogical_Tree_Admin->bp_manage_capabilities, groups_get_group_members, BP_User_Query->__construct, BP_User_Query->prepare_user_ids_query, BP_Group_Member_Query->get_include_ids, BP_Group_Member_Query->get_group_member_ids
