Googlebot doesn't find CSS or JS after latest update

After updating the new version, I could see that some parts of my website didn’t render properly (a floating bar in the bottom of the screen informing about cookie use didn’t get render and the CSS was partially broken), so I disabled the minify CSS. The site went back to normal.

Two days after updating this plugin to the latest version, Google Webmasters Tool sent me an e-mail with the topic “Googlebot can’t access the CSS and JS files”

Could you make available old versions of the plugin, so I could go back and install one that worked better with my installation?

My wordpress install is: 4.2.3

Thanks for a fantastic plugin.
