Getting Uncaught TypeErrors / SyntaxErros And alot of others Issues

I’m getting a lot of Uncaught Errors on the live page and more of them when I’m trying to edit the pages with Elementor. Majority of them are influenced by jquery.sticky.min.js .

I’ve made a clone of the website and already Updated all my plugins, deactivated all of them one by one, or all of them leting only elementor and elementor pro to be active, and I’m still getting the same erros. Almost all the time when I want to update a page with elementor im getting the 500 error and some pages are not updating.

I’ve already gave more max-memory limit on my clone website and made the max execution time bigger and got the same problems.

The admin-ajax error appears after i press the update button.

I am thinking those problems are made after an update done long time ago but I was not able to find any fix for the problem.

container.findChildrenRecursive( callback ) is hard deprecated since 3.5.0 - Use container.children.findRecursive( callback ) instead
