I was editing my survey. When I made changes to the format (font, colour, size, etc.) of the newly added questions, an error message just pop-up on the screen saying
And the formatted questions cannot be saved or published on Qualtrics. Does anyone know what is going on? Can anyone tell me how to fix that??

If this is happening with all the questions, then check with your brand administrator if your account has access to HTML editing.

It just happened today, I was able to make all these edits in the previous 50 questions. I just found this probelm when I was editing a few newly added questions today.

Best approach you should reach out to support but in meanwhile when you get this error, open the duplicate tab in new window and this error should be gone. It requires the page need to be refreshed.

I tried, but its there.
