Web.Config causes 500 internal server error

Question

This is my web.config file contents:

<?xml version="1.0"?> 

<configuration> 

    <system.webServer>
    <httpErrors errorMode="Detailed" />
        <asp scriptErrorSentToBrowser="true"/>
        <rewrite>
            <rules>
                <rule name="Main Rule" stopProcessing="true">
                    <match url=".*" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php" />
                </rule>
            </rules>
        </rewrite>

     </system.webServer>

    <system.web>
        <customErrors mode="Off"/>
        <compilation debug="true"/>
    </system.web>
</configuration>

I'm trying to use pretty permalinks of wordpress.

But this web.config files causes 500 Internal Server Error.

What is the problem?

Answer 1

The problem was from the server, they have not installed Microsoft URL Rewriting Module correctly...

The module has been installed correctly, and then problem solved.
