We’re very sorry for the inconvenience caused by the fatal error you encountered when updating to Jetpack version 11.5.
Our developers have worked urgently to address the error, and a new version of Jetpack, version 11.5.1, has been released to resolve the problem. You should be able to safely update to this version of Jetpack without encountering any errors.
To update the plugin, please navigate to the Updates panel on your WP Admin dashboard and update Jetpack. You should also see the option to update under Plugins -> Installed Plugins.
Once you have updated Jetpack, if you have currently deactivated the plugin, you can safely reactivate it after updating.
Please let us know if you run into any further issues, and we’ll be happy to help. Apologies again for the trouble!
(Now that the bug is fixed, if you feel like updating your review based on the value Jetpack provides for your site, it would be much appreciated!)
