Well everyone in DotNetNuke Universe.... I got a call from Mr. Weather.com himself and he informed me that weatherchannel.com purposely re-wrote and changed their feeds because many were using 3rd party modules I.E. DotNetNuke to implement their weather feed.
This Change which took full effect May 6, 2008 will render all DotNetNuke Weather modules that use weatherchannel.com's feed are now USELESS.
He did suggest that if the creators of such modules re-write their code according to the new SDK guidelines, located at http://download.weather.com/web/xoap/sdk.zip then it should work! (Scroll down to page 9 of the sdk pdf instructions)
So for all those who have successfully re-written the source code to their weather modules, PLEASE SHARE with us.
Thanks and we eagerly await updates
Note I have noticed that http://www.oliverhine.com is successfully getting theirs to work with out any issues yet the download of the module still appears to have issues with reading the weather feed from weather.com
