No I have not been able to reproduce the issue.
Only the client has experienced the issue.
But I am wondering if its perhaps a mac issue.
I do not have a mac to test on so I wouldnt beable to reproduce it if that were the case.
And I also wonder if its related to just her - but she hasnt experienced this on any other sites that she shops on either....
And the confusing thing is that whenever she gets this error, she is able to just redo all her steps, and finish checking out. So what leads her to have the error, when she repeats, she doesnt get the error at all. Its the same items in the cart, the same checkout info, etc.
if you have any ideas of where i should be looking for troubleshooting this, that would be great. I have asked to to call me asap the next time it happens so that i can run some tests right then. so id like to get the ideas of what to test.
my theory that i want to test is that it has something to do with the mac in particular and when the transition from the unsecured cart view page, moves to the secured checkout.
i believe that during the transition SOMETIMES the session is lost.
