We're having a problem with orders duplicating and customers being charged twice as a result with Zen Cart 1.3.8a. I read another post on the forum talking about this and offering some code tweaks, but this did us no good. In addition, we put in place a function that prevents the "buy" button from being double clicked, so the users screen is frozen while the transaction process.

We've ruled out user error completely. The date stamps on these are the exact same second and double clicking the button or refreshing the page are not possible. Something is wrong with Zen Cart and I'm powerless to fix this and its a huge problem since this is of course people's money we're talking about.

Has anyone else experienced this and NOT been able to rectify it? Any help would be greatly appreciated.
