Parsing Error with OpenWeatherMap.org

I have been using GhostXML to capture openweathermap.org dat to track estimated precipitation levels. Recently I started getting a weird parsing error. The data looks just like always does but I am not sure what the problem is. None of the custom states are there.
Any thoughts on this?
GhostXML Warning [Weather Forecast] - Return code: 3 - URL malformed. The syntax was not correct.]
GhostXML Warning There was a parse error. Will continue to poll.
Any thoughts on this?
