 * Hello,
    i get a strange trouble when i try to desactivate and activate anything,:
   SyntaxError: JSON.parse: unexpected character moreover, if I deactivate something,
   get to another menu and go back it show me the module as activated as I do nothing…
   I cannot activate anything new on the jetpack plugin like snow for Christmas 
   If I desactivate the plugin, publish something, active again the plugin , it 
   send the publication with publisize and so like I never desactivate the plugin,
   so can I teel you that peoples who get 150 mail in one shot are not very happy.
 * thank you

 * Could you let me know what other plugins are currently active on your site?
 * Could you also try the following, after installing Jetpack 4.4.1 again:
    1.  Open the dashboard page.
    2.  [Open your browser console](https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors#Step_3:_Diagnosis)
    3.  Click on the Network tab
    4.  Refresh the page.
    5.  Try to activate or deactivate a module
    6.  If you see any lines in red inside the browser console, click on them. A new
        panel should appear on the right.
    7.  Click on the “Response” tab in that new panel.
    8.  Copy the message displayed there.
    9.  Paste it here.
    10. If no red lines appeared in the browser console, click on the “Console” tab
        of the browser console.
    11. Copy any errors displayed there, and paste them here.
 * Thanks!
 * Until we find a way to solve that problem, you can use the old Jetpack Settings
   to activate and deactivate modules on your site:
    `http://yoursite.com/wp-admin/
   admin.php?page=jetpack_modules`

   question
 *  Open the dashboard page.
    Open your browser console Click on the Network tab
   Refresh the page. Try to activate or deactivate a module If you see any lines
   in red inside the browser console, click on them. A new panel should appear on

 * > no error to report…. why? ??? that the one million dollar question
 * Indeed! The lack of error is weird.
 * I can see one plugin that may block WP REST API requests on your site. Do you
   use Members to make your site private? If so, could you try to deactivate that
   option in Settings > Private, and let me know if it helps?
 * If making your site public isn’t an option, then I’m afraid you’ll need to keep
   using the old Settings page.
 * > Curiously this ([http://yoursite.com/wp-admin/admin.php?page=jetpack_modules](http://yoursite.com/wp-admin/admin.php?page=jetpack_modules))
   > is working perfectly
 * That’s to be expected, as this page doesn’t use the same method to activate or
   deactivate modules.

 * Could you then try to deactivate each one of your plugins, one at a time, and
   let me know if you find a specific plugin that causes the issue?

 * I’m not sure I can help you with lingotek, you’ll need to ask the plugin author
   for help.
 * I would be happy to take a closer look at those REST API issues, though. Could
   you contact us via [this contact form](http://jetpack.com/contact-support/) and
   mention this thread, so I can run some more tests with you?
