Help in x5

Hello,

I'm new here and although I've used WebPlus before, I haven't created a site from scratch before. I've tried to upload my files tonight and for some reason none of the images or the nav bar are showing.
I've used the in-built uploader, so it should all be in the right place, but I don't know what to look for to check!

I'm seeing this; There was an error generating the navbar:
WpNavBar is not defined

Can anyone help? My website is www.somethingborrowedmagazine.co.uk

Thanks

Eleanor
