 * Hi there,
 * As a first step here, would you please delete Jetpack and then reinstall it?
 * Try the following exact steps for a completely fresh reinstallation:
    - From the wp-admin dashboard of your site, please go to Jetpack > Dashboard
      > Connections > Manage site connection from your left-hand menu.
    - Click the “Disconnect” button. If it’s already disconnected, you can skip 
      to the next step.
    - Deactivate your Jetpack plugin by heading to Plugins > Installed Plugins and
      finding “Jetpack by WordPress.com.”
    - Completely uninstall Jetpack.
    - Reinstall the newest version of Jetpack.
    - Deactivate all of your plugins.
    - Activate only Jetpack.
    - Back in Jetpack > Dashboard > Connections > Manage site connection, Click 
      the “Set up Jetpack” button and continue through the approval process.
 * Please let me know the results of this troubleshooting and we can go from there.
   Thanks!

 * Hi there [@darnelldibbles](https://wordpress.org/support/users/darnelldibbles/),
 * Why oh why is there still no other solution for ‘deactivating all of your plugins’??
   This is a very successful website, and I cannot just deactivate all of the plugins
   just to make 1 plugin work. When should I do that, btw?
 * I’ll discuss it with these ladies and advise them different plugins instead of
   Jetpack…
 * Thanks for your response, anyhow.
 * Kind regards,
    Irene

 * I am also running into the same problem. I have turned off all plugins and my
   site is still slow.
 * I also have a site that this slow down started on last weekend and it is killing
   my traffic.
 * Help.

 * Hi there,
 * The more important step here is the fresh install of Jetpack. However, it is 
   much easier to isolate the issue and eliminate any potential conflict that may
   be causing the issue when you disable your other plugins. But, feel free to just
   do the fresh install of the Jetpack plugin and see if it resolves the issue.
