# Hummingbird – Speed Optimize, Cache

 * 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

 * Hello [@nialex](https://wordpress.org/support/users/nialex/)
 * I trust you’re doing well!
 * Please contact your hosting provider and make sure that the “**expires**” module
   enabled.
 * If it is enabled, please run a test for a conflict with another plugin. Have 
   a full backup of your site and deactivate all plugins besides the Hummingbird.
 * Go to Hummingbird > Caching > Browser Caching and re-check the Browser Caching
   status. See if all is well. Please see this screenshot:

 * If this will not help, please let us know for which file types the Browser caching
   is not shown as enabled. Also please share here a link to your site
 * Please advise
    Kind regards, Nastia
