Blank page

Hello,

I was trying the domain mapping plugin out to see how easy it will be for my clients to map their domains; I used one of my godaddy domains to test it. But for one reason or the other I have been seeing a blank page since I added/mapped the domain. I followed the steps completely and godaddy even sent me a message that I am doing a change on my domain namesavers. Am I supposed to add the domain to my hosting account for it to work because its been more than 48 hours since I mapped it and its still showing a blank page.

Please help me out.

Thanks
