Browser caching – seems not working?

Can you tell me the url please?

Thank you for your support. I give you 3 examples:
https://www.kezikonyvunk.hu
https://www.xn--akadlymentes-honlap-tub.hu/
https://www.evintech.hu/

And the gtmetrix reports showing low browser cache:

Your server is Nginx. You should add browser caching rules into config file manually.

This is not nginx but Apache/2: https://www.xn--akadlymentes-honlap-tub.hu/
Browser cache is enabled in the plugin. But cache not enabled in response headers. Would you please help me?

hmm. mod_expires.c must be installed in the server. Probably it hasn’t be installed in your server. You should contact to your hosting provider.
