Page Builder plugin breaks WordPress Customize function

After I installed the Sydney theme and the recommended plugins, I could no longer save changes in Customize (Appearance >> Customize) in the admin. Now, whenever I make changes in Customize and click “Save & Publish,” the progress dial spins and then “Save & Publish” button stays the same instead of the “Saved” status appearing. The changes don’t stick.

When I deactivated the Page Builder plugin, the Customize function worked properly.

Hello there,

Thank you for reporting. But, I can’t experience the same issue on my test site. I am running Page Builder version 2.4.25. What version are you running?
