 * Using WordPress 4.7.9.
 * Filebird 4.3.1 was previously working fine on this WordPress version. I recently
   attempted to upgrade the plugin to version 4.9.1. It breaks the javascript on
   media library page and folder control does not appear on the page.
 * Error Details below:
 *     ```
       Uncaught TypeError: d is null
           <anonymous> http://dev.ts.com/wp-content/plugins/filebird-pro/assets/dist/js/app.js?ver=4.9.1:1
           <anonymous> http://dev.ts.com/wp-content/plugins/filebird-pro/assets/dist/js/app.js?ver=4.9.1:1
           jQuery 8
       app.js:1:560821
       ```
   
 * I disabled all other plugins. Tried different themes to no avail. I receive the
   same error message.
 * Any help on this would be greatly appreciated.

 * Hi [@sajeeljintech](https://wordpress.org/support/users/sajeeljintech/) ,
 * Sorry for the late response!
    Please update FileBird and WordPress to their latest
   version, then check the issue again.
 * Also, if the issue persist, then take a screenshot of it and send us.
    Thank 
   you!
 * Kind regards,
    -Bruce-
