New Update Breaks CSS

So I use the Avada theme, which compiles CSS depending on which page you view first to initiate the compile. I have two domains, <redacted> and <redacted> using Multi Domain.

The problem is with the Font Awesome icons, which break one if compiled on the other. This was not an issue before the last update.

I remember there being a resolution to using FA icons from a different domain (CDN usage I believe), but why would this just now, after the update become an issue. Also note that Avada updated recently, so it could be an issue with the template.

Should this be a Multi Domain issue/fix, or an Avada/FA issue?

Thank you for your help!

SOLVED MY OWN PROBLEM. Need cross-origin support in .htaccess (restart apache after adding these lines).

<IfModule mod_headers.c>
  <FilesMatch "\.(ttf|ttc|otf|eot|woff|woff2|font.css|css)$">
    Header set Access-Control-Allow-Origin "*"
  </FilesMatch>
</IfModule>

I’ll go ahead and leave this for anyone experiencing the same problem.
