Why wouldn’t it let you put it in your domain? What was the error message?
Your main domain should be Fully Hosted. Is your “home” subdomain also fully hosted? When you WebFTP to your account, do you see a ilov3starz.com AND home.ilov3starz.com directories? Hopefully so.
If that’s the case, then you can use WebFTP to do the following:
- Rename ilov3starz.com to ilov3starz.old
- Rename home.ilov3starz.com to ilov3starz.com
Then use your browser to go to ilov3starz.com/wp-admin and go into Settings -> General and change the URL for your blog.
If all else fails, you can Custom install WordPress into your main site if that directory is empty.
