Hi, it’s because we cannot change cache path in W3 Total cache, and it won’t also allow to rename the default cache path. I see that you are already using Autoptimize plugin. So you can use cache plugin like WP super cache or WP fastest cache.
HMWP is compatible with Autoptimize plugin. In your screenshot above, the autoptimize urls are default ones and are not renamed by HMWP. First of all, please deactivate HMWP plugin and make sure everything is working fine. After that you can enable HMWP and start configuring it. Let us know!
