 * I use [W3TC](http://www.w3-edge.com/) on my site along with Cloudflare and everything
   has been set according to [this site](http://www.besthostnews.com/guide-to-w3-total-cache-settings-with-cloudflare/).
   It used to work perfectly without any issue but a couple weeks ago there has 
   been a following error:
 * > Recently an error occurred while creating the CSS / JS minify cache: GET[‘f’]
   > param part invalid: “”
 * I also had my site check on Google PageSpeed Insight. It suggested my to Remove
   render-blocking JavaScript and Optimize CSS Delivery for my plugins.
 * I’ve tried to clear cache and disable Cloudflare but the problem still persists.
   Does anyone know the cause of this problem
