Google Page Speed Prestashop render blocking of css file

[soduno]

I am optimizing performance at our Prestashop. So far it is okay, but I am having some problems with render blocking.

It seems that it can't load the CSS file correctly according to google.

 

Anyone has luck solving this? It seems that other prestashop sites has the same issue.

Is there a plugin, or perhaps an article explaining this?

 

Best, Simon

You have to unlock access to css files, you change in robots.txt

 

This line:

Disallow: /modules/

By:

Disallow: /modules/
Allow: /modules/*.js
Allow: /modules/*.css
