New install, Joomla 3.9.20 front end is blank - shows the template info only (Helix ultimate) but no Sppagebuilder. I can see the front end site IF I change templates.
I wouldn't call this "resolved." I was just about to update (with a back-up of course) but now seeing this I'm going to hold off. I came into the forum something else, glad I saw this.
