Can somebody help me? I am playing with asp.net. I have created simple asp.net application based on web forms. It is working on mine local computer but on helio hosting some error is generated. Framework version is 3.5. Even I cannot see the error stack. I set in the file web.config customErrors mode="Off" but still i gives me the message: The current custom error settings for this application prevent the details of the application error from being viewed remotely After searching on google it appears that settings in the file machine.config can supress settings in web.config. But I have no access no machine.config file on this server. Or maybe reason of not showing error details is completely different. I need to see errors. How can I resolve the problem. Thanks in advance
