   if ($this->obj['sql_tbl_prefix'] != "ibf_")
   {
      $the_query = preg_replace("/ibf_(\S+?)([\s\.,]|$)/", $this->obj['sql_tbl_prefix']."\\1\\2", $the_query);
   }

and remove this code.

then search for

$the_query = str_replace(",id", ",userid", $the_query);

and after this add

   if ($this->obj['sql_tbl_prefix'] != "ibf_")
   {
      $the_query = preg_replace("/ibf_(\S+?)([\s\.,]|$)/", $this->obj['sql_tbl_prefix']."\\1\\2", $the_query);
   }
