    @phatj I’ve checked the page in question and it looks like the TTFB is high, around 1.65s suggesting you’re not using a caching plugin at least on this area of the “Checkout” process. Unloading some CSS/JS will help, though I will look first into improving the TTFB which should be the first thing on the list to optimize.

    When you’re saying that you’ve edited the assets, do you mean that you unloaded some major CSS/JS files that aren’t needed? I’ve noticed quite a few when checking them via Coverage (see this post to understand how it works: This includes, but is not limited to:

    • /plugins/woocommerce/packages/woocommerce-blocks/build/wc-blocks-style.css?ver=6.7.3
    • /plugins/sfwd-lms/themes/ld30/assets/css/learndash.min.css?ver=
    • /themes/enfold/config-woocommerce/woocommerce-mod.css?ver=5.9.1
    • /plugins/wpforo/wpf-themes/classic/colors.css?ver=
    • /plugins/yith-woocommerce-wishlist/assets/css/font-awesome.css?ver=4.7.0
    • /themes/enfold/config-templatebuilder/avia-shortcodes/timeline/timeline.css?ver=5.9.1
    • /plugins/yith-woocommerce-wishlist/assets/css/style.css?ver=3.6.0
    • /themes/enfold/css/avia-snippet-widget.css?ver=4.8.9
    • /themes/enfold/config-templatebuilder/avia-shortcodes/blog/blog.css?ver=5.9.1
    • /plugins/wp-video-lightbox/css/prettyPhoto.css?ver=5.9.1
    • /themes/enfold/config-templatebuilder/avia-shortcodes/masonry_entries/masonry_entries.css?ver=5.9.1
    • /plugins/wpforo/wpf-themes/classic/widgets.css?ver=
    • /themes/enfold/config-templatebuilder/avia-shortcodes/icongrid

    You also have plenty of JS files from plugins that you likely do not need to have loaded on that page, thus, you can go ahead and unloaded the JS files from those plugins (you need a trial and error with this) and then check the page for any errors (e.g. errors in the browser’s console).

    By unloading the unused assets, you will improve “Eliminate render-blocking resources”. However, to improve it completely (e.g. there might be one or two files left there such as jQuery to be on the safe side), you will need to use a plugin such as WP Rocket that automatically appends critical CSS or even Asset CleanUp Pro that has a method of implementing critical CSS. Note that you can implement critical CSS using the Lite version of Asset CleanUp too, but it requires editing a PHP file (e.g. functions.php from your theme):

    thanks for replying Gabe

    There are 2 pages

    I can load the assets and null them in
    and the pagespeed score is pretty decent.

    but the assets do not load in
    so I cannot null them. It just hangs at
    Step 2: Build the list of the fetched assets and print it… Please wait…

    @phatj it’s very likely there is a JS error there when the output is returned from the AJAX call and if something is not right, it will just not print. I’m considering updating the plugin to print something when there are JS errors. This happens rarely, I have to admit that. So, what you can do is have the browser’s console opened the moment the fetch is made. Just right-click on that page, “Inspect” and then click on “Console”. Let me know the errors that are likely printed there.

    Also, please the “Direct” retrieval method (otherwise private pages could not be read and that could be the reason behind the errors) in “Settings” — “Plugin Usage Preferences” — “Manage in the Dashboard”.
