By Default ASP.NET scripts do not show actual error message in browser for security reason.

It will be helpfull to show the error message to browser when installing or developing a script.

To enable this, create a file “web.config” with following content and upload it to your web sites web root (the folder in which you upload index file.)

<configuration>
<system.web>
<customErrors mode=”Off”/>
</system.web>
</configuration>
