I’m getting an admin-ajax 403 error when clicking the Join Group button. It seems to be the switch case in the functions. It seems to be completely ignored somehow. Logging within any of the cases returns nothing at all. Also a quick note… it’s not every group. It’s only on random ones

function bp_legacy_theme_ajax_joinleave_group() {

	if ( ! bp_is_post_request() ) {
		return;
	}

	// Cast gid as integer.
	$group_id = (int) $_POST['gid'];

	if ( groups_is_user_banned( bp_loggedin_user_id(), $group_id ) )
		return;

	if ( ! $group = groups_get_group( $group_id ) )
		return;

	// Client doesn't distinguish between different request types, so we infer from user status.
	if ( groups_is_user_member( bp_loggedin_user_id(), $group->id ) ) {
		$request_type = 'leave_group';
	} elseif ( groups_check_user_has_invite( bp_loggedin_user_id(), $group->id ) ) {
		$request_type = 'accept_invite';
	} elseif ( 'private' === $group->status ) {
		$request_type = 'request_membership';
	} else {
		$request_type = 'join_group';
	}

	// NOTE: WHY IS THIS BROKEN?!!?
	switch ( $request_type ) {
