 * Hello.
 * Our data indicates that your site has WP-Cron deactivated by defining the constant`
   DISABLE_WP_CRON`. The constant is usually defined in the file `wp-config.php`.
   It can also be disabled by hosting provider, so you might reach out to them about
   it.
 * If WP-Cron is disabled, there should be an external scheduler (e.g. Cron) running
   for WordPress to function properly, otherwise scheduled events will not be executed.
   The issue is not Jetpack-specific and is likely to affect other plugins or even
   WordPress itself.
 * More on WP-Cron here: [https://developer.wordpress.org/plugins/cron/](https://developer.wordpress.org/plugins/cron/)
 * Please let us know if you get any further questions.

 * Hello [@crisdb](https://wordpress.org/support/users/crisdb/)
 * >  1. Activate Jetpack and configure it with default modules (Security, Performance,
   >     Anti-spam).
   >  2. Use the Masterstudy registration form (built into the theme).
   >  3. Try to register a new user from the frontend form.
 * Unfortunately I wasn’t able to reproduce the problem by following these instructions.
 * Testing it on your site, I see that there’s an error returned (but not displayed)
   by the registration form:
   `{"errors":[{"id":"required","field":null,"text":"Il
   campo \u00e8 obbligatorio"}],"status":"error"}`
 * The error is a translation of the `Field is required` error, which is triggered
   in the file `masterstudy-lms-learning-management-system/_core/lms/classes/user.
   php`. It is not triggered by Jetpack itself.
 * However, there does seem to be a plugin conflict. If possible, please provide
   more detailed instructions to reproduce it, and we’ll try to debug the problem.
 * It might also help to ask the MasterStudy developers for additional details on
   the “The third party plugin is blocking cookies.” issue they mentioned.
 * If there was a widespread cookie issue caused by Jetpack, we would see it with
   other plugins or even WordPress itself. It appears to be a conflict with this
   specific plugin, and we would appreciate any pointers that would help us get 
   it resolved.

 * Hello [@edent](https://wordpress.org/support/users/edent/).
 * Thanks for bringing it up. We’ll give it a closer look and see if this is something
   we could optimize.
