Very strange, Stuart.
The message seems to indicate that it’s failed to recognize the _xql parameter in the URL. I can’t see any reason offhand why that should happen. What’s the exact URL that you’re using? Can you try some variations on it, e.g. changing the order of parameters, changing _xql to _xql[], changing it to uppercase, etc?
If the trace option is on, then all parameters in the URL should be logged. What does the log say?
