I get the following error when i start the site for the first time after running the web installer.

I am running with the following specs

Windows Server 2003
SQL Server 2008 R2
Visual Studio 2010
Kentico 5.5

I choosed the following in the web installer:

.NET 4/2010
IIS

I only choosed to install the ecommerce site.

What could be the cause of this error ?

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

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

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
