I’m having the same issue. I can’t add a new gallery because it doesn’t show either in the editor or the preview.
Hi Onur,
Thank you for fast reply 🙂
I’ve disabled the one other block plugin I had but it hasn’t made any difference. Not sure if it can be caused by a conflict with other plugins than block plugins?
I’ve tested the issue a bit more and it seems I can make the tab text bold, italic and strike-through without the paragraph inside disappear. Once I pick any of the other options the error occurs. If I then remove the style, the paragraph comes back.
I tried to go back to WP 5.2.3 but that didn’t work either.
Very strange, but I’m sure there’s a good explanation somewhere 🙂
