W3 Total Cache – Minify doesn't appear to be working

Hi,

For my website, I am using W3 Total Cache. I have all the minify settings turned on (like https://www.wpcub.com/w3-total-cache-settings/), but I’m not sure that it is actually minifying anything.

I also have it turned off “Prevent caching of objects after settings change”, to prevent it adding query strings after the js and css files, but it is still getting all the query strings.

Here is the speed test results page that shows my issues:

Any idea what is wrong with it?

My website address is https://www.cohesiveit.com.au

Thank you.

Regards,
Chris
