  Hello, I tried to update JetPack today to the latest version, the update failed, and I can no longer update JetPack. When I attempt to activate the JetPack update, I get the following error:

  Plugin could not be activated because it triggered a fatal error.

  Fatal error: Cannot find a library with slug admin-pages/class.jetpack-landing-page. in E:HostingSpaceschuckc3managedagile.comwwwrootwp-contentpluginsjetpackrequire-lib.php on line 22

  I tried to delete the JetPack plugin and reinstall it failed in the same way. Can you please advise how I can resolve this problem?

  Thanks,

  Hi there,

  There are a number of reasons that an automatic update could fail. Jetpack is a large plugin, with many modules and language files. This can cause issues with some servers when using the automatic update.

  Could you please try manually reinstalling Jetpack? To do so, download the Jetpack plugin here:

  http://downloads.wordpress.org/plugin/jetpack.latest-stable.zip

  Then, log in to your site via FTP, and delete the existing Jetpack plugin folder. You should then be able to reinstall the plugin manually by following the instructions here:

  http://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation

  I would strongly recommend that you make a complete backup of your website before trying this.

  I hope this helps! Please let me know if you have any questions. :)
