 * Hi [@adrianrus9](https://wordpress.org/support/users/adrianrus9/),
 * Browser caching is server side thing and Hummingbird tries applying the rules
   via .htaccess to set the expiration values.
    However, in order to have this working
   you need to have “expires” module active on your server and also for your host
   to allow these changes to be made via .htaccess rules. Please get in touch with
   your hosting provider and ask them about the above things so they can check this
   further for you.
 * Cheers,
    Predrag

 * Hello and thank you for using Hummingbird. We are going to close this ticket 
   for now because we have not heard from you in a while. If you still need support
   we can reopen the thread.
 * Cheers,
    Predrag
