Arrrgh!

It's sorted now. Last night and most of yesterday I was trying to get this fixed. I had installed brand new zencarts (no template Diva - I think you missed a post while you were typing your last one), installed, uninstalled, deleted, started again and always got the same problem.

Today I turn on my computer and it just works. WTF? How is that possible? When I refresh the page I hit f5 as well to clear the cache. Obviously it's got something to do with SESSION but how unbelievably frustrating, what a huge waste of time
