Browser 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
If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.
