[Hummingbird] Hummingbird: Browser Caching is not working properly

The "Browser caching" tab has the following error:

"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"

The htacces is correct and the module "mod_expires for Apache" is active, can you help me?
