Link only works for Home Page

I accidentally trashed the Home Page. I also did a few other chores just before that but they were not unusual. The link to all pages on the site was destroyed and only the Error Page pooped up when the URL was typed in. I was able to get into Admin and restore the Home page. Now, the hme page can be accessed but none of the other pages can be accesssed…..get the ERROR page message for all. I can see them all in Admin but the public cannot get into it. This is a club web site, not a blog. How can I restore the links to the other pages.
