page builder content not visible when viewing live page

Hi – every time I tried to save my edits in page builder, the whole page content disappeared. So, I have changed the save.php file (as per help in the forums), which has solved the saving problem, but now I can’t see my page builder content in the live view.

Could be because I’ve updated to latest version of quest. Please can you help me with a new save.php code?

Also, the function of being able to copy / duplicate modules and sections isn’t working for me since I upgraded – I found it a useful feature please can you help me get it back?
