Building chat room in website using telerik components

[Ei Wai]

Hello,

I am trying to develop a chat room on our website. When I was searching, I found this article. I download the project and tried to run it on my local pc. It is working fine until Register When I login, it goes to Chat page,page load event,then it showed 500 error. Does anyone tried to run that project and face the same issues? Can anybody help me?

Thanks in advance.

Best regards,
Ei Wai
