Error loading stylesheet: An unknown error has occurred (805303f4)

@athemeart We’re sorry to hear you are experiencing this issue on your site.

If the XSL file does not load, it may be blocked. You should speak to your host provider and confirm nothing in your .htaccess file is preventing it from loading.

It’s expected because WP home/site URLs are set as www. So, www version should work, but non-www throws this error.
