    In the latest version we are seeing:

    Fatal error: Uncaught Error: Class ‘Automattic\Jetpack\Third_Party\domain_map’ not found in /home/webeasy/webapps/webeasy/wp-content/plugins/jetpack/3rd-party/class-domain-mapping.php:156 Stack trace:

    Fix is line 160 of 3rd-party/class-domain-mapping.php change from:

    return domain_map::utils();
    return \domain_map::utils();

    Hey @slightlydifferent,

    Can you please deactivate and delete Jetpack entirely, and then reinstall it?

    You can delete Jetpack from your Plugins page in WP Admin. Then, you can reinstall from the Plugins page as well. Here’s our guidance on doing this, if you need it:

    Then, reconnect to Jetpack.

    If you still have trouble, could you please post your site URL here, so we can do some targeted troubleshooting?

    Thanks for the report! That does indeed seem related to some changes we’ve made in the latest version of Jetpack, and your proposed fix should solve the issue. We’ll make sure to include the fix in the next version of Jetpack.

    You can follow our progress on this here:

    We’ve just released Jetpack 9.3.1 to address this issue. Everything should now be back to normal once you update to that new version of Jetpack.

    Sorry for the trouble!
