I have the latest free version installed (updated today) on WP 6.2. When I try to enter a CFF form either by adding a short-code block or by adding it with the CFF block, it gets added to the page edit but when I click on the Update tab, I get this error message: “Updating failed. The response is not a valid JSON response.”
I can’t provide a page link because there is nothing to show. I cannot add a CFF form to any of my pages.
