 * replace this code in line 361
 * `if (in_array( $the_post->post_type, $this->post_types ) && ! preg_match( ........`
 * with this
 * `if (is_array ($this->post_types) && in_array( $the_post->post_type, $this->post_types)&&!
   preg_match( ........`
 * In this new code we are just checking that the 2nd parameter is array.
