Hello,
We have purchased SP Page Builder Pro and installed it on one of our sites. When creating an article or page with the backend editor, it displays perfectly when saved. However, when reopening the page or article editor, the backend returns a blank page, as if there is no content, although if you access the page or article on the frontend, it displays correctly.
Apparently, the backend does not detect the id of the PB element that you want to edit and loads as if it were a new page or does not find the content.
We have SP Page Builder Pro 5.3.0 installed on a Joomla 4.
