Hi, Thanks for the suggestion. But as I said, when I turn Fiddler on to take the trace, it works fine and the error disappears. Any idea why that might be?

Please contact administrator Hello It's a bug in the Mid Tier. The stack trace is trying to convert a string, I assume read from the request, to a number. The string is empty and hence the parse fails, leading to the exception (which should be caught and handled, but isn't). I think you'll need to collect a Fiddler trace to find out what request is causing this to happen, as that's the root cause.
