Problem: When having Toolset Views active and Elementor Pro we cannot edit a post with Elementor on the front end. It says it must have `the_content()` enabled on the post to work fine. As soon we disable the Views plugin this is solved.
Solution: Most certainly you have assigned a content template to a post, and then edit that post with Elementor. That's not possible. You should instead create templates or post designs with Elementor, and in those, insert Content Templates if required using Elementor widgets for Content Templates.
