The error indicates that the files are likely ok, but the file edits to load the page are missing. These edits are usually else statements based on a $main variable. You may have been asked to put these in skin1/single/home.tpl. Any changes to that file, ensure they were also made to skin1/admin/home.tpl, or pull them out of skin1/single/home.tpl and put them into skin1/common_templates.tpl
