This is urgent and I am simply LOST. I have "All In One Developer Package LifeTime" and have been using Pagebuilder for some years now. Most of my older content was edited with JSN Pagebuilder and a very small part with JSN Pagebuilder 4.
My problem now is that I can´t edit any of my older articles created with JSN Pagebuilder. When I open the article, I only see this "loading page symbol" in the middle of the page, but the page NEVER loads.
What is going on?
The installed version is JSN PageBuilder PRO STANDARD for Joomla! 3.x.
DevTools show me this:
"Failed to load resource: the server responded with a status of 500 ()"
The articles created with JSN Pagebuilder 4 are working fine, but those created with the other editor do not load at all. Yes, I have cleaned cache, changed browsers, etc. No clue.
