I have been having problems with jetpack since I did the update this morning. It worked just before I did the update.
I try to reinstall older version but problem remain.
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!
I do it.
Other problem, scheduled posts don’t published when time arrived.
