Hello,
I was updating one of my pages from Joomla 3 and PageBuilder 3 to last Joomla 4 and last PageBuilder 5. Everything seems to work fine. Only saving in frontend editor doesn't work. It does work when there is only like 2 sections on the page, but after more content is added then the save button just rotates infinitely and never saves. However in the backend editor it saves completely fine no matter how much content on the page there is. Is there any solution to this? Thanks.
