Internal error 500.

I do not know how can i fix it?I change my web config but it dose not change

Answer 1

In your web.config file add the following:

<configuration>
    <system.webServer>
        <httpErrors existingResponse="PassThrough"/>
    </system.webServer>
</configuration>

This will ensure upstream errors are rendered to the browser.

Answer 2

I was having same problem on a new Windows 2012 Server.

In IIS manager, at the site level, I had also set properties for ASP for send errors to browser to true, but was still getting the generic message in my browser (I am accessing the site from another PC, not locally on the server).

I went into error pages, and clicked 'Edit Feature Settings' to find this dialog window:

Change setting from 3rd option: Detailed errors for local requests and custom error pages for remote requests To 2nd option: Detailed errors

Answer 3

Open your website in browser on server or modify your web.config file to allow showing error on client browser

<customErrors mode="Off">

Then it should give more detail about this error.

Or you can check your server event log.

Answer 4

请试试这个：

Error Pages -> 500 -> Edit Feature Settings -> "Detailed Error"
