What do you see when you click that link? Even if your wordpress in installed on a sub folder or a test folder (IE: church.com/test you should still be able to see the main page of your wordpress site when you click that link. If your domain is pointing to a different location IE:root vs. your new wordpress directory then when you go to your domain name IE: church.com you will see your old files, not your new ones. How do you have wordpress installed – where is it installed in your file structure of your site? Do you have a link to your site we can view?
