I think I met a bug but I’m not quite sure.

It comes from a template I made for membership by this shortcode :
[eme_if tag='#_IS_USER_MEMBER_OF{FurWest 2019-2020}' value='0']

The guilty 303 line :

function eme_get_member_by_wpid_membershipid($wp_id,$membership_id,$status="") {
   global $wpdb;
   $members_table = $wpdb->prefix.MEMBERS_TBNAME;
   $persons_table = $wpdb->prefix.PEOPLE_TBNAME;
   $status_expired=MEMBER_STATUS_EXPIRED;
   if (empty($status)) {
	   $cond_status="members.status != $status_expired";
   } elseif (strstr($status, ',')) {
	   $cond_status="members.status IN ($status)";
   } else {
	   $cond_status="members.status = $status";
   }
   <strong>$sql = $wpdb->prepare("SELECT members.* FROM $members_table as members, $persons_table as persons WHERE members.membership_id=%d AND $cond_status AND members.person_id=persons.person_id AND persons.wp_id=%d LIMIT 1",$membership_id,wp_id);
   return $wpdb->get_row($sql, ARRAY_A);</strong>
}

Could you please help me ?
