Divi with WP optimize – caching issue

Hi,

It sounds like what’s happening is when DIVI is regenerating the static CSS files and the page is currently cached it’s pointing to CSS files that no longer exist.

One thing I would recommend checking with the DIVI support team is to see if there is an action that we can hook into when the CSS regeneration happens so that we can trigger a cache purge.

Let me know if they have something available and I can provide a code snippet that will trigger a cache purge when they regenerate the static CSS files.

Hi,

Thanks for sending that over. I wasn’t able to find anything in the documentation but I did find something in the changelog from a 2023 release.

I just want to verify something, when this broken layout happens does purging the WP-Optimize Page Cache resolve the issue?

Also, the next time you notice it can you send me a link to the page? I want to check the error console to see if what my theory is for the problem is correct.

Thanks!

Hi,

Thanks so much for the update! Definitely keep me posted and if the issue returns I believe I found something we can hook into for when Divi regenerates its static CSS files so that we can tell WP-Optimize to purge the cache.

Thanks!

Hi @jchambo,

If my theory is correct and the issue is that Divi is regenerating their static CSS assets, can you try adding this snippet to your theme functions.php file or as a new php file in the mu-plugins folder? I was able to find a hook that Divi uses when their static assets are removed and can call our function to flush the cache.

add_action('et_core_static_resources_removed', 'my_clear_wpo_cache');

function my_clear_wpo_cache(){
    if(function_exists('wpo_cache_flush')){
        wpo_cache_flush();
    }
}
