You can control all of Jetpack’s features from one simple page.
As the number of Jetpack features has grown over the years, we made the decision to simplify our interface. We now activate our most useful features by default upon installation, so those don’t appear in the primary Settings interface.
If you still want to control whether or not these popular features are on or off, or you simply want to control all of Jetpack’s features from one page, you can find them directly at a URL like this:
[yoursite.com]/wp-admin/admin.php?page=jetpack_modules
Simply replace “yoursite.com” with the actual domain of your site.
You can also find a link to this at the bottom of any Jetpack page in your site’s Dashboard:

You know you’ve landed in the right place when you see the following list:

The blue line on the left indicates that the features is active. Click the boxes next to the various features to turn them on and off as desired.
When you hover over a feature, you’ll see different options appear based on whether the feature is active or not. You can also use the Activate and Deactivate buttons to control the status of the feature.
The Configure button that appears for activated features will take you to the configuration area in the admin dashboard for that feature.
