Exception on some sites - Failed to read the 'cssRules' property from 'CSSStyleSheet'

[mwanchap]

Hey there,

I've tried CSSVacuum (using the Chrome store version) on a bunch of different sites and often it works fine, except for the one site I actually want to use it for :( It's behind a login so I can't link you to it, but another example of a site it doesn't work on for me is this one: https://www.centrepointalliance.com.au/?CSSVacuum.

I see the following exception logged in the console:

Uncaught DOMException: Failed to read the 'cssRules' property from 'CSSStyleSheet': Cannot access rules
