 * I am using plugin latest version. But i can’t activate or deactivate modules.
   When i click activate or deactivate links, white screen appears.
    Also i can’t
   disconnect jetpack within site dashboard but i can disconnect it from wp.com

 * I’m sorry to hear you’ve run into issues.
 * Could you check your server error logs around the time when you experienced the
   issue, to find out more about the error?
 * If you don’t know how to access your server error logs, your hosting provider
   should be able to help.
 * Let me know how it goes.

 * Yes, there is an error. I find this in error log
 * > PHP Fatal error: Call to undefined method Jetpack::is_staging_site() in /home1/
   > mysite/public_html/wp-content/plugins/jetpack/class.jetpack-sync.php on line
   > 173
 * I don’t know what is this.

 * It seems that you’re missing some of the updates that were made to the last version
   of Jetpack.
 * Could you try to log in to your site via FTP or CPanel, and delete the existing
   Jetpack plugin folder, and reinstall the plugin manually as explained here:
    
   [http://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation](http://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation)
 * You’ll find the Jetpack plugin folder here:
 *     ```
       wp-content
          plugins
            jetpack - DELETE THIS FOLDER
       ```
   
 * If you’re not sure how to do this, you can ask your hosting company for help.
   They should also have documentation explaining how to edit or remove files from
   your site using FTP or a File Manager in your admin panel.
 * Let me know how it goes.

 * Thanks [@jeremy](https://wordpress.org/support/users/jeremy/)
    After delete and
   reinstall, all is going right. Lot of thanks.
