Cache 404?

Hi,

Thanks for a great plugin. Was checking the logs and find a bunch of cache 404s which seems odd to me? They can look like this:

https://www.mysite.com/wp-content/cache/min/1/wp-content/plugins/comments-widget-plus/assets/css/cwp-ee09569de573a3f5b0c6ea6a8b6ec7f9.css

That file name is likely just a randomly generated name by the looks of it, so ignoring that one will do nothing as new ones pop up. Any idea what this is and what I can do about it?

Kind regards
Dan
