Server Error in '/' Application. ASP.NET

Question

Greeting,

I developed a website using ASP.Net 3.5 and C#. It is working good with Visual Stdio 2010. I uploaded my website to my domain under the public folder.

Answer 1

This wont necessarily fix the problem...but it will tell you what the real problem is.
Its currently trying to use a custom error page that doesn't exist.
If you add this line to Web.config (under system.web tag) it should give you the real error.

<system.web>
    <!-- added line -->
    <customErrors mode="Off"/>
    <!-- added  line -->
</system.web>
