    Hello,

    I hope this message finds you well. I am currently facing an issue with LiteSpeed Cache and its ESI (Edge Side Includes) functionality. I am using WordPress with Breakdance Builder and WooCommerce, and I have implemented LiteSpeed Cache to cache the entire website.

    The specific problem arises on the “Single Product” and “Products Archive” pages, where I have conditional text that changes based on the time of day. Before 12:00, one text is displayed, and after 12:00, another is shown. Caching these URLs causes an issue as the cached content doesn’t update with the correct time, leading me to explore the ESI feature.

    I have created a shortcode that utilizes ESI, like this: [esi myshortcode]. The shortcode successfully retrieves the desired text based on the time of day. However, I am encountering two main issues:

    1. Duplication: Occasionally, the page renders with duplicated content, appearing twice in a stack.
    2. Incorrect Rendering: In some instances, instead of rendering the shortcode, the entire HTML of the page is displayed within the shortcode.

    I have observed a peculiar message, “nonce_ajax:5c12a891cf,” on the product page during some occurrences.

    Notably, when I insert the ESI shortcode on a blank page (containing only header and footer), it functions correctly without any issues. My question is: Is there a way to exclude this specific element from caching, allowing the rest of the page to be cached effectively?

    Here is working fine: https://menajeando.online/esi-blocks/

    Any insights or suggestions to troubleshoot and resolve this matter would be greatly appreciated.

    Thank you in advance for your assistance.

    Best regards,

    from what you said , I think it might be better idea to schedule a purge on the time it changes

    How could I do that? Through a cron job? Can you give me an example?

    Thanks

    does this take place on all of the product category and product page ? or certain few of them ?

    In all Single Product, Shop Page, Home and all categories. The best thing to do would be to purge the whole page, right?

    I tried this option but could not find a way to schedule it 2 times a day, at 12pm and 00am.

    So I decided to create two cron jobs at each of the times I need it to call a cron_purge.php file with this code:

    <?php
    require( './wp-load.php' );
    if ( defined('LSCWP_V')) {
    do_action( 'litespeed_purge_all' );
    }

    As explained here:

    And it works!

    @qtwrk Thanks for your help
