Suddenly can't add javascript to the code editor

Never had an issue adding to Custumize > Code > Javscript Code.

Now suddenly for one of our client websites - It displays the following when trying to save. Even tried using the code that is currently there and just added a comment. It still won’t save.

  • HTML detected, the “JavaScript Code” setting only accepts Javascript.

Any ideas?

Are you including script tags? If so, that box only accepts Javascript.

If you want to use Script tags, try in Code > Head instead.
