Hello,
as mentioned in this post https://www.joomshaper.com/forum/question/29087, my HOME page has disappeared - the good news is that it hasn't happened since then that the whole content of a page disappears!
What has happened though - heading bars have disappeared :)
Fortunately, I'm currently redesigning the site - it's a lot of work, not only because of the number of pages and the planned redesign, but also because of the problems caused by the SP Page Builder updates!
Fortunately, I've made a copy of the page from which I can retrieve the headings - but it's not normal!
What else I can say: SP Page Builder version 5.2.3 works reasonably well - there are certainly a few little things that could be improved - e.g. the editor that is used for a text add-on.
This editor behaves quite strangely in some respects - I always have to switch to the system editor, which is JCE in my case, so that I can format the pages correctly!
regards
