Thank-you for the reply, I have submitted a support ticket.
I did not understand the User Submission setting and got that figured out now. For some reason Show Submission turned to ON on all my FAQs, possibly after a plugin update.
So we’re only dealing with a 500 error when saving in Elementor now.
And now I simultaneously have another issue. The Add FAQ button (for user submission) is showing on all my FAQ widgets even though I have User Submission disabled in Settings. Can’t get them to go away. I wonder if it happened after the last plugin update.
I also found that limiting the FAQ’s to 6 solves the problem. That’s not going to work on this scenario but at least I can keep building on this page for now.
