@danishhaidri Asset CleanUp has been tested successfully with WP Fastest Cache. After Asset CleanUp unloads the chosen CSS/JS, WP Fastest Cache is taking the remaining loaded files and minifies/combines them. Also, the resulting HTML source code is cleaner & cached by WP Fastest Cache.
Note that if you already enabled minify/combine CSS/JS in WP Fastest Cache, the same feature will be automatically disabled in Asset CleanUp.
