Yikes, then I'm currently stuck with a shopping cart that doesn't work.
I've read a couple of times on these forums where it's been mentioned that perhaps developers are too quick to release updates. I have to agree in this instance.
Yesterday I had working shopping cart. Today I have a very unhappy client and no sign of a resolution.
OFF: Sorry, but if you not so experienced, WHY do you upgrade modules on the production site whithout checking them on the test environment first?
