I'm just wondering if anyone else has/had the same problem that I do and knows how to fix it?
I already have a congo account. I login and go through the checkout procedure right till choosing the postage meathod etc. Then when it's the final step, the cart disappears and returns to the home page. This happens with ozebaby, clothpadshop and a number of other shops that use congo cart.
Any ideas?
It's been happening for ages - and has occasionally prevented me from hyenaing something that I've really wanted (not always though!). Not to mention that it's a PITA to email someone and get them to take it off the shelf for me
So if you know how to fix it PLEASE HELP ME!
