 * Hi,
 * HI am performing an audit on my website, using gtmetrix tool. It suggests me 
   to eliminate render blocking resources. I have something like 10 css files , 
   that have these paths:
   xxxx[/cache/wpo-minify/1683903294/assets/wpo-minify-header-xxxxxxx.min.css](https://edurocket.it/wp-content/cache/wpo-minify/1683903294/assets/wpo-minify-header-learndash_quiz_front_css4.5.3.min.css)
 * I tried to add these css under the “**Load the following CSS files asynchronously**”
   box, and it works.
 * The problem is when the cache updates, than the folder “[1683903294](https://edurocket.it/wp-content/cache/wpo-minify/1683903294/assets/wpo-minify-header-learndash_quiz_front_css4.5.3.min.css)”,
   updates to a new values so, **the path is not correct any more**.
 * I am not sure how to fix the problem, since if i try to specify the name of the
   css file using something like *[wpo-minify-header-xxxxxxx.min.css](https://edurocket.it/wp-content/cache/wpo-minify/1683903294/assets/wpo-minify-header-learndash_quiz_front_css4.5.3.min.css)
   to allow any base url, it does not get matched. So the matching for async css
   loading appears to be working only when specifying the full base url, but **it
   changes** as I wrote before!
 * Is there any way to provide a correct dynamic matching, based on a part of the
   url or file name only or any work around?

 * Hi,
 * Apologies for the delay over the weekend, we are currently investigating/replicating
   this.

 * [@nedberto92](https://wordpress.org/support/users/nedberto92/) You shouldn’t 
   load minified and merged assets. Instead you have to find out which resource 
   is actually render blocking and load it asynchronously. You can disable minify,
   and use GT metric to find out that.
   Also when minify is enabled, you can exclude
   the render blocking assets from Minify => Advanced tab. Please refer screenshot

 * Thankyou very much. I will try with this approach !
