Preview is blank, won't update when typing in code and the "Run tests" button is unresponsive

Challenge Use a CSS Class to Style an Element has an issue. User Agent is: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.101 Safari/537.36. Please describe how to reproduce this issue, and include links to screenshots if possible.

Hello,

The code preview on the right hand side of the page is completely blank and will not update when new code is typed into the editor. Also the “Run Tests” button is unresponsive. I have tried to use three web browsers: Goggle chrome, Firefox and Safari. All three web browsers have the exact same problem so I think perhaps there is something wrong with the FCC site currently or there is something wrong on my end. Is this a common issue? Any help would be appreciated.

Thank you

My code:

<style>
  .red-text {
    color: blue;
  }
</style>

<h2 class="red-text">CatPhotoApp</h2>

I am reporting an issue with the site itself. I have no problem with the challenge.

Note: I realize the code in the screen shot should be Class=“red-text” not “blue-text”. The issue remains.

A work around that performs for me is to refresh the browser until the tests show up and the display functions. (Usually not more than 3 refreshes).

The tests will usually be marked as passing at this point, but you’ll need to run them again.

When that stops working (around 5 lessons), I close the browser window and open https://www.freecodecamp.com/ in a new window.
