ASP.Net Problems

[group39]

I have a couple of sites running under plesk. I recently tried to do a simple asp.net test page and I am getting and error. I have a web.config file in the root of my site I am using that will allow the error message to be shown to remote computers. The site is not recognizing it because I just get the default error page that tells me to set this in web.config
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>

That is already set. Anyone have any ideas on how to fix this issue.

Thanks
