The background colour of the Instagram title band seems to have gone missing. There was an issue with the widget and i had to remove and re-install it. The colour band has been missing since then. Could you help restore it please?
Yes, after adding a widget, WordPress gives it a new “id number”. It does not matter if the widget is exactly the same that the other one that was placed in, WordPress automatically gives a new number.
So yes, after deleting and adding a new one, you need to modify the CSS.
