where is the yellow warning icon in ie9

does anyone know how开发者_StackOverflow do we enable the yellow warning icon in ie 9?

Click the gear at the top right and choose Internet Options, then go to the Advanced tab and uncheck the "Disable script debugging (Internet Explorer)" option. After applying your settings it should now attempt to debug any errors it comes across.
