I have seen this for 3 different websites now, having trouble editing using the frontend page editor on Elementor if Rocket Loader is enabled. This is weird because it should just load the JS minified/async but apparently it will break Elementor plugin.
So that sucks. You can’t use Rocket Loader if your WordPress has Elementor?
If you’re WordPress site “breaks” from Rocket Loader it’s a good sign your theme is way too bloated… the only way you could get a conflict is if your theme has a shit load of JS scripts.
