I know that by disabling helix ultimate js compression, sp page builder front-end editing works. When are you going to fix this so that even enabling it works?
In the helix options I have inserted these files: main.js, jquery.min.js, sppagebuilder.js
But it doesn't work anyway.
Is the problem to be solved in helix ultimate or in sp page builder?
