Hi, the replacements you added here (https://d.pr/i/24eO15) is not correct. It will replace all CSS class names and script variables starting with word ‘elementor’ and hence will break your site.
You can check the Replace Tools tab for the replacements I have added, and are replaced in page source – https://www.screencast.com/t/x2Df9tC2Di
You’ll need to add replacements accordingly. But it’s not recommended to replace CSS class name like elementor-element, elementor-position-top, etc as it might break the site.
