These settings are incorrect:
You ordered a total of: 1 Min: 0 Units: 0

You cannot order minimum 0 nor Unit 0

Defaults are:
unit 1
minimum 1
maximum 0 for unlimited

New Products default is 1 on hidden box ...

Configuration ... Product Info ...
Setting should be 1 ...
Product Quantity Box Status - Adding New Products
What should the Default Quantity Box Status be set to when adding New Products?

0= off
1= on
NOTE: This will show a Qty Box when ON and default the Add to Cart to 1
If this isn't happening ...

Your clean install ... I am assuming you mean really clean as in nothing added ... not add-ons or templates or anything ...

I cannot understand the defaults being off ... unless changed ... and if they are set right ... why are they not working ...

When you say clean install ... is this a download from us or an autoinstall via something like Fantastico?
