I am using WP Super Cache plugin on my website http://www.prosoccerrebounder.net/ and I recently checked my site on google page speed insights. I am getting the following fix message
"Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network."
Can I fix this problem via WP super cache settings like through garbage collection?
My current cache timeout is 604800 seconds and timer is 604800 seconds too. I use Autoptimize plugin as well.
Anyone's quick help is appreciated.
