    Hello.

    My web portal use MSSQL Server and ASP.net, I changed my portal admin password but when I want logging to my portal via new password then I got:

    Server Error in '/' Application.
    
    Runtime Error
    
    Description: 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. 
    
    Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
    
    
    <!-- Web.Config Configuration File -->
    
    <configuration>
        <system.web>
            <customErrors mode="Off"/>
        </system.web>
    </configuration>
    
    Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
    
    
    <!-- Web.Config Configuration File -->
    
    <configuration>
        <system.web>
            <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
        </system.web>
    </configuration>

    How can I solve it?

    Thank you.

    Hello,

    You should change the <customErrors mode="Off"/> in your web.config, so to see the error details.

    Regards

    I go to "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config" and the content of "web.config" is:

    <?xml version="1.0" encoding="utf-8"?>
    <!-- the root web configuration file -->
    <configuration>
        <!--
            Using a location directive with a missing path attribute
            scopes the configuration to the entire machine.  If used in
            conjunction with allowOverride="false", it can be used to
            prevent configuration from being altered on the machine
    
            Administrators that want to restrict permissions granted to

    Hi windows.geek,

    I go to "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config" and the content of "web.config" is:

    Change this web.config will affect all the websites that hosting on your server, it's better to check the web.config file which locates at the root folder of your website.

    Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

    This exception means that some become null after you change the admin password and login use the new password. Please try debug your application in VS and check which value become null.

    And could you please share your logic code here? So I can check which line of code may lead to this exception.

    Best Regards,

    Jean

    Do not change the config file on C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config location. As changes you will make here will have effect on every website you will create.

    Rather change it in your application's web.config file. Can you please post your application's web.config file so that I can guide you with exact location where you have to place customerror tag.

    Thanks

    Hi,

    It is written to the Windows event log by default. I would suggest to check that for now.

    And you'll enhance your error reporting process later when you won't be hardpressed by solving a real world error.
