Hi,

You have the following declared twice:

<location path="vehicle">
    <system.web>
      <authorization>
        <allow roles="admin"/>
        <deny users="*"/>
      </authorization>
    </system.web>
  </location>

remove one of them and you won't get the error.

Best regards
Johan

i have removed this when still i get this error :

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

 Config section 'system.web/authorization' already defined. Sections must only appear once per config file. See the help topic <location> for exceptions

when i publish the site using file system and check the option for precompile during publishing. i get this error again

I guess because you have 2 locations for vehicle

Answer 4

Hi shan,

Based on the error message, the reason is the authorization of a path has been defined multiple times.

However, you said that you still get the error even though the section as valuja said has been removed.

So, I suggest that first, please try to clean the project and rebuild, then check the result.

On the other hand, please remove all location sections and add a location after each time succeed test.

Thanks

Best Regards
