Hi, well that’s really my problem, all the mod files compare completely, I’ve had the host check every error log and security log and php.ini files at their end. I have checked the confirmation pages and they are the same both sites have all the same mods and zencart version so I’m thinking I have corrupted or a file has been corrupted at some point but I have no idea where to look.
But because the callback is the obvious place I was hoping to find a file or set of files I could compare to the other site. I guess it could be at any point in the checkout but I have no ideas where to start.
