 * There is an error validation in **is_valid_date** function, in **/modules/date.
   php**
 * The variable format is comming like ‘dd/mm/yy’, but the code is doing a strtotime
   without convertion to database format ‘yy-mm-dd’.
 * To solve it, I changed the code:
 *     ```
       if (! empty($value) && ! self::is_valid_date($value)) {
       			$result['valid'] = false;
       			$result['reason'][$name] = wpcf7_get_message('invalid_date');
       		}
       ```
   
 * to:
 *     ```
       $value = explode("/",$value);
       $value = $value[2]."-".$value[1]."-".$value[0];
   
       if (! empty($value) && ! wpcf7_is_date($value)) {
         $result['valid'] = false;
         $result['reason'][$name] = wpcf7_get_message('invalid_date');
       }
       ```
