just broke my site

Hey, Sorry Karlson about your experience. I suggest you follow this guide to get your problem fixed: https://docs.elementor.com/article/677-faq-for-elementor-3-0

Let me know if there’s something I can do to help

Pff… 3.0.0 update killed my internet store.
So I immediately killed Elementor from my website and moved to othe solution.
Have no time and resourses to spend on untested releases.

Are you using Elementor Pro with Dynamic Functions ?
Have you recently edited your Custom Posts or taxonomy terms,\ This could be sometimes becasue of Editing the Post Terms when you use Elementor Pro Post or Page templates..

I used free version and did not edit anything.
Upgrade of Elementor killed the website…
