You may have to make some changes in the menu.
Go to Appearance – Menus and then from the “Select menu to edit”, choose “Menu 1” (or something, I’m not sure of the exact name).
You should see a menu entry called “Home”, and you should be able to open it and change the URL that it points to. Currently to http://wallkillta.fatcow.com, change it to http://www.wallkillteachers.org.
If you don’t see that in there, maybe the menu is set in some other place in the theme options.
your answer fixed the problem…thank you Senff.
