Sometimes the locally cached thumbs are not visible; only after CTRL + F5

    Hi,

    It is not an end-of-the-world problem ?? but I am just curious what sometimes causes the YouTube thumbs – that are cached locally – not to be displayed in a post. First, I thought it had smt to do with clearing my server cache (Siteground), for example after publishing a new post or saving an edited post, but I have not found a correlation between the two.

    When I press CTRL + F5 the thumbnail always appears and remains displayed for a while.

    So I am wondering if anyone has an idea?

    I am also using Autoptimize and Async JavaScript with the following settings:

    – Status Enabled
    – Method: Defer
    – jQuery: Defer
    – Autoptimize Status: Enabled
    – Autoptimize Method: Defer

    Furthermore, I have added script to my .htaccess file which enables GZIP compression and leverage browser caching.

    The YouTube thumbs are set to be cached locally.

    I am looking forward to an answer.

    Thanks and regards,
    Bark

    Afternoon Bark;
    The thumbnails are loaded late -after domcontentloaded- using JavaScript, so this might very well be due to JS-errors. Maybe check the console for errors?

    Good idea Frank! As soon as I have more info, I’ll get back to this forum.

    Hi Frank,

    Well, this morning I came across a Javascript error that resulted in a YouTube Lyte thumb not being displayed:

    Screenschot of Javascript error

    After pressing CTRL + F5 it was gone and the thumb appeared.

    I hope you can say smt meaningful about it ??

    Thanks and regards,

    maybe try adding lyte to AO’s comma-separated JS optimization exclusion list? that way even in case of such JS errors in the AO’ed JS-file, the thumbnails will load.

    Hi Frank,

    Thank you for helping me with this matter. I have added the two relevant Javascript files to the exclusion list: lyte-min.js, lyte.js

    Probably it will be solved now.

    Thanks and regards,

    hmm, except if you have “also aggregate inline JS” off you need to exclude lyte to ensure the inline JS isn’t aggregated.

    Haha, Frank from Belgium. Well, this is Bark from the Netherlands ??

    I already experienced the effect of what you wrote here above. The thumbs were displayed, but incompletely. So I added lyte to the exclusion list and voila problem solved!

    Thanks!
