My RSS Viewer always in "Retrieving Data" mode but can't show anything. It just says that it retrieves data. In Sharepoint Designer 2010 on the RSS Viewer area a message displays. It says ;
"The server returned a non-specific error when trying to get data from the data source. Check the format and content of your query and try again. If the problem persists, contact the server administrator."
Why does it happen?
