Yes – I know. This is not the problem. The problem is that some pages are set up differently to others. If I set the size to “cover” – it works on the delivery page (a standard page) – but not on all the other theme pages. The container seems to be of different sizes so the background shifts.
Looks like the theme cant use backgrounds reliably…..
I really need you to look more closely at this – more than a cursory glance – there is a problem…
