Something really freaky is going on...
If you go to this site here
You will see there is a shop.
It has its own databasae and files
I have set up a copy of this site here http://www.maxtemp.com.au/upgrade
It is using a completely different database and different site files.
If you update one of the carts in either site, its shown in the other...
WHY ON EARTH WOULD THIS BE HAPPENING??
