    Thank you for your patience

    OK, so:
    1. do you get the error on all pages of your site? yes, all page front end, not admin page
    2. do you also get the error on a (test) page that was not created with Elementor (so a “normal” wordpress page/ post)? every page, i cant open every page front end
    3. do you also get the error when all options in Autoptimize (JS, CSS, HTML optimization) are off? yes, when i off them, web is ok
    4. do you see any relevant information in the PHP error logfile? no

    additionally; does the error happen when logged in, or also when logged out? all

    OK, let’s zoom in on AO settings; can you try just disabling CSS or JS or HTML or Image optimization (incl. lazyload) to see if there is a specific setting triggering this?

    aha, good. now with that option off and you visit the frontend in an anonymous browser window (so not logged on), is it OK or broken?

    i off Combine CSS files? and off : Also optimizing for editor/admin accounts?”,
    i think it’s ok… thank you so much. I’m so grateful,

    ah, CSS files …

    1. did you have “also aggregate inline CSS” on and if so can you try if disabling just that also solves the problem?
    2. if not can you try adding plugins/elementor to the exclusion list (this excludes both elementor and elementor-pro) to see if that helps?
