Test URL: URL is not cached

Your Dynamic caching is not working. Either disable Cloudflare or enable Full page caching on Cloudflare – both available in the plugin. Once you do that your site will work way faster. This has nothing to do with the cPanel to Site Tools migration.

I am not using Cloudflare, never enabled it.
Ok I understand it has nothing to do with migration, any other clue?

One of your plugins is sending a no cache header that instructs our system not to cache it

curl -I -X GET https://guidotramontano.com
Cache-Control: no-store, no-cache, must-revalidate
Pragma: no-cache

Thanks for your reply. It seems that deactivating the plugin Formidable Forms makes the cache work again, but TTFB is still over 2.3 seconds. I opened a ticket with Formidable to no avail. Can you please point me in the right direction to solve this? Many thanks!

It’s still not working on my end:

when you test, make sure you test twice because the fist hit generates the cache. You need to get

x-proxy-cache: HIT

if your caching is working properly. In that case TTFB is around 100-200ms depending on where you’re testing from since it’s mostly networking.

Sorry I re-activated the plugin that’s why it’s still not working. Now I deactivated it again and test URL is working but TTFB still slow. Tested twice as per your advice. Can you please make a test now and see if cache is working? Sorry I don’t know how to do that.
Thank you very much, I appreciate your help.

As I said above, you need to use dev tools -> networking -> headers of your site and get an:

x-proxy-cache: HIT

Your caching is still NOT working.

Something in your website keep sending Cache-Control: no-cache, must-revalidate, max-age=0

which disables our cache. I am afraid I can’t help you more with that. I would recommend contacting a deveoper to check why your site is sending those headers.
