Final tweaks on small Prestashop

I've been slaving to learn prestashop and customize a default bootstrap theme for my friend's flower essence biz in Hawaii at: [login to view URL] This shop is so close to opening and needs an expert push to finish! It has several hundred products in half dozen categories shipping in US and internationally. It looks fine, and all the rules and hooks seem to be in order, yet things keep going wrong, such as: 1) Payment error 10426 2) Blank product page 3) No order confirmation The first two have been fixed (tho prestashop seems fairly fragile). Now we need help on the third. On checkout, you’re taken to the shop’s Paypal page, and returned to the checkout page after confirming the Paypal purchase…yet there is no order confirmation, nor, indeed, any order generated. Hard to imagine how this could be, but we separately need help figuring out this final bug. Plus, we need: 1) an international shipping option on the shopping cart 2) Paypal only checkout with account/registration disabled And there will likely be a continuing tweak assistance role for the right coder. Let me hear from you soonest. kauaianken
