I noticed the following error in the Console for my website:
(index):1 Access to Font at 'https://hb.wpmucdn.com/fonts/fontawesome-webfont.woff2?v=4.7.0' from origin 'https://www.sferafitness.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.sferafitness.com' is therefore not allowed access. The response had HTTP status code 403.
I believe there is an issue with Hummingbird that causes this error to appear. Could you take a look and see if this is something that can be easily fixed? I granted support access for you to take a closer look
