No, I didn’t.

Yes, sure. Anyway, I haven’t enabled browser caching in your plugin. Once I enabled browser caching in settings, it seems that it resolved the issue. Interesting.

Yes, I can.
Once I downgrade to 4.3.2., it’s OK.

Hello.

Just try to enable structured data for example for posts (https://rankmath.com/kb/rich-snippets/) and also enable your plugin for posts (insert there the author box). Then log out and try to visit any post with the author box.

I think it only works used as a Must Use plugin. Did you try it?
in “wp-content” folder create folder named “mu-plugins” and then to that folder insert php file with the code I provided. You can name the php file like you want, for example “disable_plugin.php”. So, the full path to the file will be “wp-content/mu-plugins/disable_plugin.php”

Hi.
I don’t know if it’s useful for you but as a workaround I use the following code. It completely disables the W3 total cache when editing/updating category/tag. I use it as a Must Use plugin but I think it could also work in functions.php. But I haven’t tested it yet.

<?php

add_filter('option_active_plugins', function ($plugins) {
    $url = 'https://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

    if (strpos($url, 'edit-tags') !== false) {
        unset($plugins[array_search("w3-total-cache/w3-total-cache.php", $plugins)]);
    }

    return $plugins;
});

Hello Marko Vasiljevic.
Any news here? Were you able to reproduce the issue on your end?
Thank you.

Hi.

Yes, the Policy is set exactly this way. I just created fresh new WP install and it is still doing the same thing. Once I update category, the whole cache is cleared. Please check the video.

The Purge log is available only in Premium.

Are you sure about that?
I disabled all plugins except for W3 Total Cache and also tried to change the theme to Twenty Twenty-Two, Twenty Twenty-Four, Generate Press and it’s still doing the same thing.
Once I update any category, the whole cache is purged. It’s doing the same thing also on my other web.

Radan

Hello.

It’s not the case. The cache is cleared everytime no matter what I set in the purge policy. Just everytime I update the category.

Thank you for your help.
I understand but I would rather clear and preload the cache all at once in some given interval. So what I did now is that I disabled the priming of the cache automatically ind your plugin and instead I use this code:

/*w3tc preload manually*/
// Schedule the event
add_action('init', 'schedule_pgcache_prime');
function schedule_pgcache_prime() {
    // Get the current time in the Prague time zone
date_default_timezone_set('Europe/Prague');
$current_time = current_time('timestamp', true);
// Get the current hour and minute separately
$current_hour = date('G', $current_time);
$current_minute = date('i', $current_time);
		
if (($current_hour == 0 && $current_minute >= 10) || ($current_hour == 1) || ($current_hour == 2 && $current_minute < 10)) {
        // Schedule the event to run every minute
        if (!wp_next_scheduled('w3_pgcache_prime')) {
        wp_schedule_event(time(), 'every_minute', 'w3_pgcache_prime');
		}
	   }
		else{
	// Unschedule the 'w3_pgcache_prime' event
wp_clear_scheduled_hook('w3_pgcache_prime');
	}
}

I am also calling w3tc_flush_all(); before the preload begins.
So, now the cache is cleared at 0:10, and then preload starts from 0:10-2:10 which is enough to finish it and then it stops. It’s true that I am using pretty aggressive preload 30pages/minute.

I found out that this problem is caused by Rank Math SEO.

Ok. And what to write there?

It didn’t. Everytime I update/save post, the categories are purged.

Oh, so that’s why the conversion took so long ??
Ok, now I understand.
Thanks.
