Periodically, and apparently randomly, when I load any page with a DNN RSS Module the modules crash with a "Critical Error" and they don't display any information.  Sometimes it happens on initial page load and sometimes it happens when navigating backwards from the RSS story.

I'm running News module version 4.0.0.1, and it happens across different computers, browsers and when tried from different networks. I don't see a detailed error message... only Critical Error, then the RSS boxes are minimized.

Any ideas??

Thanks,

Robert

Thanks very much... didn't think to check there. This appears to be the error message associated with the crash. It happens very randomly every few days and has no apparent pattern when it occurs.

I am getting a similar error.

When the page loads IE throwns this error:

Sys.Webforms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

Log viewer reports this message:
