Background problems

Hi First off I would like to express my incompetence so I’m sure this will have a obvious solution
as you can sea there the background of the image is a checkered and quite ugly


their is a copy of my world settings as you can see I want the background white im completely stumped so I hope someone will be able to help thanks in advance

In Render / Film settings ensure you have not enable ‘Transparent’ to make the background transparent (indicated by a chequer pattern)

Thank you so much I knew it would be simple :o
