The browser caching was properly enabled by Hummingbird (the rules were added to the .htaccess and its working based on GTMetrix as an example). However, Hummingbird is still mentioning:
rowser Caching is not working properly:
– Your server may not have the “expires” module enabled (mod_expires for Apache, ngx_http_headers_module for NGINX)
– Another plugin may be interfering with the configuration
What can we do?
