@mikehermary Have you performed a conflict test yet?

Try deactivating all plugins except for WP-Optimize and see if it is resolved.

If so, reactivate each plugin one at a time until you find the culprit. You can check for the issue between activating each plugin, so you can see which one is causing problems.

Please let us know your findings.

@dg78 You can use wpo_pre_cache_bufferhook to alter content to be cached

add_filter('wpo_pre_cache_buffer', 'function_to_filter'):
function function_to_filter($buffer) {
  // alter the $buffer
  return $buffer;
}

You may purge cache on wp_login and wp_logout actions

Since it is header content I think the caches are continuously generated.

If, All you want to do is to serve different version of cached file for logged in users and logged out users, then you can buy our premium version and enable cache per role option

@marketwo WP-optimize scan the sitemap.xml for urls, so it takes time to preload the urls, at the moment there’s no option to speed up the process.’

Multiple page cannot be loaded at once at the moment.

You can purge the minified files from WP-Optimize > Minify, in-order to delete the mifiy files from the server.

Or Please use following snippet and add it to your active child themes functions.php file, it will automatically delete the minified files after 3 days

add_filter( 'wp_optimize_minify_cache_expiry_time', function( $original_value ) {
return time() - 86400 * 3;
} );

@ittone Could you please try to purge minified files from WP-Optimize > Minify and check if you still get 404 errors?
