PixCams Elementor Problem

I have a website that's designed in Wordpress. The site is: https://pixcams.com/. Recently when I was making updates to the site they didn't show up. I could see the updates while in the Wordpress environment, but once I logged out I could no longer see them. I tried all of the normal stuff with clearing the cache and uninstalling plug-in's I wasn't using. Nothing worked. The editor for the Wordpress site is Elementor. That plug-in needed an update, so I updated it. Things got worse. Now I get this message when trying to edit a page "Preview Could Not Be Loaded". I desperately need help! I can't seem to fix this.
