BUG: shortcode in date-query not applied

Hi,

Just noticed, that the w4pl shortcodes for date and time are not applied in the helper-posts-date_query.php file.

Please add the following snippet in the parse_query_args function, on line 219.

          // parse shortcode from date values, this allows to use dynamic values
          if( is_array($dq['value']) ){
            $dq['value'] = array_map('do_shortcode', $dq['value']);
          }
          elseif( !empty($dq['value']) ){
            $dq['value'] = do_shortcode($dq['value']);
          }
