Two sites and one domain? Another iweb issue

When I click visit in iweb, it takes me to this site

www.mendedheartstherapy.com/Mended_Hearts_Therapy/Home.html

However, when I type in www.mendedheartstherapy.com it takes me to an old version of the site.

The first website is the latest update. I don't get it...

I'm seeing the exact same site on both. Try refreshing your browsers cache as it may be storing the old site offline for you.

I had my web host company forward the other domain to the domain that looked right. I think that's why they're exactly the same ???

You need to change both DNS records (A-records) in your hosting account to your IP address (both www and @)
Mostly the changes are applied in 24 hours or less
