Leverage Browser Caching not working

Check if your htaccess has all w3rc rules descibed in the “install page” of w3tc.

@nigrosimone:Yes, as far as I understand. You can find the full htaccess below. Any suggestions to resolve this? Thanks

See the rules… sometime you can see some line eg <IfModule mod_expires.c> this mean the rule need mod_expires module installed on the server. Maybe, your server doesn’t has all required module. Contact your hosting.

Hello,
I see that line, and mod_expires is installed on the server:
This module is installed.
—
root@host [~]# httpd -M|grep expire
expires_module (static)

Any other ideas as to why it’s not working? Cheers!

You can post a lint to your website?

Sure (it was also in the OP): The URL is pkookshop.com

Cheers!

Seems its an issue with the pingdom tool e.g. its serving up an old cache version of your page with the previous expiration time value u had.

When using the more comprehensive GtMetrix site instead you can see from the following link your problem doesnt occur and you can even see the response headers under the Waterfall tab that they are indeed sending back the correct expiration times: https://gtmetrix.com/reports/www.pkookshop.com/STmt4aBv
