 * Hello,
 * I have been trying to install Jetpack but kept getting an error message saying
   it was already installed. When I looked into the issue I read a thread that suggested
   going into my websites hosting page and deleting Jetpack in the control panel.
   I did this then successfully reinstalled jetpack. When I went to activate it 
   I received the following error message.
 * Fatal error: Cannot redeclare class Jetpack in /home3/andybarton/public_html/
   wp-content/plugins/jetpack/class.jetpack.php on line 25
 * I would love to finally install Jetpack. If anyone can point me in the right 
   direction I would be very grateful.
 * Kind Regards,
 * Andy.

 * It does indeed sound like Jetpack is already installed on your site, most likely
   via another directory.
 * Could you make sure that there is no other Jetpack folder under `wp-content/plugins`
   or `wp-content/mu-plugins` in your WordPress installation?
 * Let me know how it goes.

 * Hi Jeremy,
 * Thank you for replying to my message. I have now deleted everything Jetpack under
   WP-Content/plugins in my Hostgator account.
 * Should I now reinstall Jetpack?
 * Regards,
 * Andy.

 * Yes, you should now be able to reinstall Jetpack by going to Plugins > Add New
   in your dashboard, and searching for “Jetpack”.
 * Let me know how it goes!

 * Hi Jeremy,
 * I tried again and the same error message came up. The folder Jetpack still remains
   in the sidebar but I have deleted all its contents.
 * Could it be the JP-CUSTOM-CSS?
 * Regards,
 * Andy.

 * Yes, that could definitely be it; you don’t need that plugin since its features
   are already part of Jetpack.
 * Let me know how it goes!

 * Hi Jeremy,
 * Wouldn’t I lose my page if I delete the custom CSS?
 * Kind regards,
 * Andy.

 * You can copy the CSS before you deactivate and delete the plugin, and paste it
   under Appearance > Customize > Additional CSS in your dashboard.
