I have a simple webgui application that I'm trying to display, just some controls, no code. When I type <my domain>/Webguidemo.wgx in the address bar I get a Server Error '/webgui' application Runtime Error. The page that displays just has the following message with no details as to why the error occurred. An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. DASP has mapped the .wgx extension in IIS6 so what could be the problem? Can someone give me some tips on how to debug this as DASP support is saying this is an application problem and not a DASP problem. I don't know how this could be if I'm just trying to display a wgx page. Regards
