publicize tick boxes not active

When i click on edit settings within a post both of the tick boxes are blank and it is not possible to put a tick in them.

That’s indeed the expected behaviour when looking at posts that are already published. Could you check these boxes when looking at a draft post?

If you experience the same issue there as well, can you please use Jetpack’s Debugger module to send us some more information about your site?

1) Go to the Jetpack page in your dashboard.
2) Click on the Debug link appearing at the bottom of the page.
3) Click the link that says “click here to contact Jetpack support.”
4) Fill in the description box and your name and email address.
5) Click the “Contact Support” button.

Thanks!
