We are currently running Cart V4.3.1 and need to upgrade to fix a known bug. We use a theme named Summit. It's a responsive theme from cscarttemplates.com. Any thoughts on which version to upgrade to that is proven stable and reasonably bug free?
Capcha Security
I've read other posts where the Capcha security causes a road block for customers to check out. And it can't be turned off. Is that true?
Anything else to be wary of in upgrading?
