1. Most Common Issue : Can’t Edit with Elementor Page Builder and Seeing, That rotating Wheel.
It’s issue of your Server configuration. You need to make your Memory Limit to 768M. Wondering Why? Because As using Addons plugins are common. On an average most elementor sites have 3-4 Premium Addons. Each Addons have multiple widgets in that. All those widgets, Have to load all of their CSS and JS in the backend, When you edit the page. So, Combination of all CSS and JS of all widgets, Make it heavy to load backend. At that time, You need higher memory limit to make your backend work.
