I have a aspx page and it displays custom error but i can't see a detailed error message. My web.config looks like this,

<?xml version="1.0"?>
    <configuration>
    <appSettings />
    <connectionStrings />
    <system.web>
        <compilation debug="true" />
        <authentication mode="Windows" />
        <customErrors mode="On" />
    </system.web>
</configuration>

To see the error you need customErrors off, like this:

<customErrors mode="Off"></customErrors>

From the docs, here are the options for the mode attribute:

  • On - Specifies that custom errors are enabled. If no defaultRedirect attribute is specified, users see a generic error. The custom errors are shown to the remote clients and to the local host.
  • Off - Specifies that custom errors are disabled. The detailed ASP.NET errors are shown to the remote clients and to the local host.
  • RemoteOnly - Specifies that custom errors are shown only to the remote clients, and that ASP.NET errors are shown to the local host. This is the default value.
