Invalid public shared ip address in platform server configuration for shared IP address usage

Yesterday, I was installing WebSitePanel (WSP) 2.x for a client. After successful installation, when I tried to create a website, WSP showed an error message and failed to create website. Error was "Invalid public shared ip address in platform server configuration for shared IP address usage". 

After a little search, I found this article:
http://www.websitepanel.net/making-the-required-changes-to-your-iis-service-global-dns-records-to-support-websitepanel-2-0/

However, when I checked settings of WSP, Public Shared IP addressed was already there.

Drilling the source code of WSP revealed that WebServerController.cs looks for a Service Property "PublicSharedIP". Looking at the ServiceProperties table in WSP database, I found that this properly "PublicSharedIP" does not exists!!

So, I executed following query to add "PublicSharedIP" property into database:
INSERT INTO ServiceProperties (ServiceID, PropertyName, PropertyValue) VALUES(2, ‘PublicSharedIP’, 1)

(1 is my Public IP, listed in IPAddresses table)

Problem Fixed!!
