wordpress - Cannot use $this as parameter in contact-form.php -


i trying run wordpress using xampp theme 'total' themeforest.

it says

fatal error: cannot use $this parameter in /applications/xampp/xamppfiles/htdocs/wp-content/themes/total/framework/3rd-party/contact-form-7.php on line 38

i referred this link , other websites outside of stack overflow too.

the code contact-form-7.php follows, 

<?php /**  * contat form 7 configuration class  *  * @package total wordpress theme  * @subpackage 3rd party  * @version 3.6.0  */  if ( ! class_exists( 'wpex_contact_form_7' ) ) {      class wpex_contact_form_7 {          /**          * start things          *          * @version 3.6.0          */         public function __construct() {              // remove css - theme adds styles             add_filter( 'wpcf7_load_css', '__return_false' );              // remove js             add_filter( 'wpcf7_load_js', '__return_false' );              // conditionally load js             add_action( 'wpcf7_contact_form', array( 'wpex_contact_form_7', 'enqueue_js' ), 1 );              }          /**          * load js conditionally          *          * @version 3.6.0          */          public static function enqueue_js( $this ) {             if ( function_exists( 'wpcf7_enqueue_scripts' ) ) {                 wpcf7_enqueue_scripts();             }         }      }  } new wpex_contact_form_7();

here's did,

i first installed in office computer , worked perfectly. tired implement same in personal laptop.

hence copied htdocs folder , replaced in laptop. exported , imported database phpmyadmin.

try removing $this, e.g.

public static function enqueue_js() {     if ( function_exists( 'wpcf7_enqueue_scripts' ) ) {         wpcf7_enqueue_scripts();     } }

see code @ gist.
