The weird thing is the only template I had touched is the checkout, to remove the shipping estimate and tax bit.
Yesterday, and looking back it may be something to do with this.... I created a test customer and a customer group to allow free product ordering… ie. regardless of price they get 100% discount.
It may have been around this time that it went screwy. However, deleting both customer and group doesn’t seem to make a difference.
In case my working copy was wrong, I over-wrote that with the most current release, which to me should have just returned the store to it’s normal templates… but alas, not.
I’ve checked all the product settings and they are allowable in catalog and search. The puzzling thing for me is that the add to cart is showing and working on the category and front pages, but not on actual product listings....
Can you think of any other way, apart from a full reinstall, and then using an export of the database?
