Database / Site Setup Help And other small issue

Hello, I have a small issue that just appeared out of nowhere and I need it fixed and adjusted inside my admin panel that affects my homepage. Also I want to use a site layout for one of my sites on another new site I am creating and need help possibly cloning a database I have for one site and using it on another site so that I can use the site layout correctly. When I upload the layout and coding for the new site it is linking everything to my other site. For example: Main site = [login to view URL] Second site = [login to view URL] I am using the site layout from [login to view URL] for [login to view URL] but when I upload the layout and files, it still links everything, including urls and content to the mainsite. For example, on [login to view URL] it will say [login to view URL] or [login to view URL] instead of [login to view URL], [login to view URL], etc NEW FREELANCERS ARE WELCOME! If you can intern for this job, there will be must more work for you in the future. If you cannot, my budget is $15.
