Need quick help with Website Redirecting

I am doing a basic redirect. I purchase a domain URL from godaddy and set the forwarding with masking to an advertisers landing page. The problem comes when people type my domain URL into their address bar this message pops up before being redirected:

"This page is asking you to confirm that you want to leave - data you have entered may not be saved."

How do I disable this? I'm not scripting anything as i've only done a basic redirect. Thanks in advance for anyone who can answer this.

It seems that you want to disable the unbeforeunload alert messages for your page. Are you using an advanced theme for your website? if yes, than you need to go to the plugins line and disable or remove the "autosave". If you want I can explain you what beforeunload fuction do?

1and1 doesn't do that thank goodness!
