I've got at problem with a Ucommerce webshop. Everything works fine and also the checkout part where you pay in the gateway (Epay/Bambora), get sent back to the website ("Thanks for your purchase bla bla.."), gets the confirmation email successfully, basket clears, everything seems fine until you after your first purchase tries to add another product to the basket.
Then it throws either "Sequence contains no elements" or "No basket exists for the current user" error page. The only solution I have is to delete the basketid cookie. So my quick fix is to make my success page automatically delete this cookie when loaded (The landing page after gateway checkout). But in rare instances if you fail to load this page but checkout still goes through, the customer will get this bug unless they delete the cookie.
I've reinstalled Ucommerce several times, but it seems to be an error in the database (I've also upgraded 2-3 times). I just don't know where to look or what it could be.
Appreciate any help! The relevant log errors:

Nice! I thought it didn't work at first, but turned out I can't have the !HasBasket()/delete cookie thing as part of my addtobasket post function. It has to be done on page load before I try adding a product. So checking HasBasket and deleting the cookie on page load (in my rendermvccontroller) works, and Ucommerce can finally figure out to create a new basket then. Might be a context thing.
Ucommerce 9 - Checkout bug
Hi guys

Everything works fine and also the checkout part where you pay in the gateway (Epay/Bambora), get sent back to the website ("Thanks for your purchase bla bla.."), gets the confirmation email successfully, basket clears, everything seems fine until you after your first purchase tries to add another product to the basket.

Ucommerce.Api.ITransactionLibrary.HasBasket();
if that returns false you have to delete the cookie or create the new basket and assigning the guid to the basket cookie.
and then proceed to adding the product to the basket.
