Many thanks in advance Roy

Nice theme, a shame the your logo does not fit the picture and looks completely out of place.

I have no clue why you get the Page not found your infopages and adding to the cart/checkout works.
Looks like it is related to your template.
What happens if using the default theme?

ive changed back to my default template and i still get the same problem and yes i know about my logo i need to revamp that bit lol
