Loutka,

I have discovered that two of my customers have upgraded accounts which appear to have been working perfectly in LIVE mode for some time. Now that I know they have been upgraded I have been able to do some testing on them. One of them works perfectly in TEST mode (apart from the no VISA payment option issue) and the other also works but I get a warning message in IE just prior to callback asking if I want to view both secure and non secure elements on the page. If I click 'Yes' the callback completes successfully.

I have no idea why I am getting this warning message in IE - it doesn't happen in Firefox - and for only one of the accounts although I am using the one Zencart site for testing both. This warning is not necessarily a security issue. It just means that IE thinks there are some elements on the page which are being called by http rather than https e.g. a script or image called from an external URL. My guess is that this may not happen on a live transaction and even if it does it's an annoyance rather than an issue.

I suggest that now the callback is working in TEST mode you try putting through a low value LIVE transaction to test what happens in LIVE mode.

If you do this could you please post back here with the result.
