Problem: your roll-back-version page says, “Afterward, go to the bottom of this page and download your preferred version from the ‘Previous Versions’ section. Problem is that there is no Previous Versions section at bottom of the page.
I am using SiteGround. They did a ‘super flush’ of all caches which cleared up the problem for about 2 hours but then it reappeared. So I deactivated Essential Addons which resolved the problem. I really needed several of the features in Essential Addons so I deactivated all the features except for 3 that I needed and then reactivated Essential Addons. It has been working o.k. now for about 14 hours.
I’ll try to email you the Elementor System Info.
Thank you.
