I am using Hummingbird Pro in my Multisite Network to check and enhance sites performance.
I have also enabled Browser Caching with resources expiry set to 8 days in cloudflare as recommended in the plugin settings.
It is working fine for main site in multisite.
But this effect is not showing in sub sites.
When I test performance of sub site, it shows that images and other resources expiry is not specified.
Please explain how to resolve this.
