Syntax Highlighting gone

Hello,

as i opened my first function node today, i realized that the javascript highlighting was gone.
Its like there no syntax detection. no automatic "",() and so on.

Is there a way to get it back ?

If node red is not running in the background and the browser is already open, you will still see node-red editor but the necessary files will not be served. Refresh your browser and check that node-red is actually running.

Also are you using ace or Monaco?

Lastly, could you check the browser's console for errors?
