CORS issue with Survey project

I’ve been working on the Survey project for the first certification, and I loaded it up today to get this error in the F12 console:

Access to Font at ‘’ from origin ‘codepen’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘codepen’ is therefore not allowed access.

It worked fine yesterday and I didn’t change anything except for add a group of radio buttons. All of my other pens are still working too.

Here’s the pen I’m having problems with:

Can anyone tell me what I’m doing wrong? I’ve searched this forum and google and all of the answers seem to involve some settings on your server, which I don’t have control over.

Now it’s working, but only because my codepen is failing to load the test scripts:

Loading failed for the with source “”.

Is there a bug with the project test suite?

I don’t know. Those cors fonts issues are a common problem with CP and have nothing to do with you - you can get them on an empty pen.

I did notice that you were loading that test script twice - once in the HTML and once in the settings. I don’t think that was the problem. Maybe it was just a glitch.

Hmm, okay. Well I guess it’s working now. Thanks!
