1. browser caching: "If re-checking and restarting does not resolve, please check with your host or open a support ticket with us." -- Not sure how to fix this. I am re-activating another plugin, WP Super Cache, until we get this feature of Hummingbird working. Can you walk me through the solution?
2. "gzip is not working properly. - Your server may not have the "deflate" module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX)"
