Browser Caching is not working properly

This is a multi-site using Apache installed via Bitnami installer on Windows 2016.
Installed Hummingbird and getting this error. Please advise.
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

    Hey Ernie !
    Hope you are having a great day!

    I'm sorry about the matter that you're experiencing this issue. I have the following suggestions for you:
    1. It seems the 'expires' module is not enabled in your server. Please get in touch with your host and ask them if it is disabled, if yes, to enable it.
    2. If the 'expires' module was already enabled, please initiate a plugin/theme conflict test following this flowchart.

    Hope this helps. Let me know what the results are. Thanks!

    Best,
    Nahid.
