I’ve checked your website and I can see that the W3 Total Cache is enabled * ``` ``` * In the compatibility check not detected means you don’t use mod_php mode, so you probably use php-fpm. We cannot detect Apache modules in that case, but that doesn’t mean it is not installed/active. I’ve also checked the Page speed insights and I can see that you have CSS render-blocking issue. Which can be solved with minifying and “Eliminate reader blocking CSS by moving it to HTTP body” option. As for the images and expires header, I’ve checked your website and one of your images /wp-content/uploads/2020/03/Formazione_Sicurezza_1.jpg and I can see that expires header is set as well as the cache control and ETag by W3 Total Cache. Please check the screenshot [here](https://imgur.com/4XghSsE).

As for the mentioned image, id toes have expires header but it’s set for 30 days. You should check your .htaccess for other directives that might be interfering with W3 Total Cache rules.

No other plugins. * This is my htaccess. It’s only w3: * # BEGIN W3TC Browser Cache AddType text/css .css AddType text/x-component .htc AddType application/x-javascript .js AddType application/ javascript .js2 AddType text/javascript .js3
