Runtime error

Note:An application error occurs on the server. The current custom error settings of this application Disable remote viewing of detailed information about application errors (for security reasons ). However, you can view it in a browser running on the local server computer.

Details:To enable others to view detailed information about this specific error message on a remote computer, go to the "Web. create a <mermerrors> tag in the config file. Set the "Mode" attribute marked by <customerrors> to "off ".

<! -- Web. config configuration file --> <Configuration> <System. Web> <Customerrors mode = "off"/> </System. Web> </Configuration>

Note:Modify the defaultredirect attribute of the <customerrors> Configuration tag of the application to point to the URL of the custom error page. You can replace the current error page with the custom error page.

<! -- Web. config configuration file --> <Configuration> <System. Web> <Customerrors mode = "remoteonly" defaultredirect = "mycustompage.htm"/> </System. Web> </Configuration>

Today, I encountered a very strange problem. The server reported the above error, but the configuration section in my configuration file defines mode = "off", which means that no error message is displayed.

Finally, remove all other settings in Web. config and leave one
<System. Web>
<Customerrors mode = "off"/>
</System. Web>
It turned out to be running normally, and I added other content to the configuration file, still running normally! The problem is solved in this way!
