Cindy:
Here is how you remove/modify the “Welcome To The Frontpage” message . . .
1. Open your site administration
2. Go to your Menu Manager – select your Main Menu
3. Select your “Home” menu item (or whichever item you have designated as the default menu item – usually it is “Home”)
4. On the right hand side, click the Page Display Options tab
5. Within the Browser Page Title field, change or remove the language.
I checked your backend configurations and this is exactly what you have in place to correct this issue.
I left it in place so you can follow the steps – and learn form the experience. 🙂
Hope that helps
EDIT:
Or, as my esteemed colleague, khoand, raced to provide – you can also choose “No” for Show Page Heading.
