Voting doesnot work by two domain name both domain names direct to the pligg site at the same time: the voting script cannot work (Cross Domain problem ?)

I have two domain names pointing to the same site.
I have two names refer to the same site.

They are:
As:
Http://clin003.com/beta/
Http://i0day.com/beta/

The clin003.com domain name is used when pligg is installed.
Install by clin003.com

The following shows how to access the site through i0day.com using ie7.0, and then log on to the webpage error dialog box for voting.
++ Ms ie 7.0 ++
When I vote on i0day.com, I got a error message like this

Because the official website is an English site, I had to translate it into English ..
