Hello -\r\nI am the web developer for a friend who

Hello - I am the web developer for a friend who has an Apple computer and uses Safari. I amended some web pages last evening, and the new pages are definitely uploaded to her site. However, when she pulls up her site, half the changes will not show. She's restarted her machine, and even turned it off/on. When she tries to reload the pages, it simply jumps her back to the Home page. I devleoped the site in Dreamweaver, using the Frames feature. Any ideas why her pages won't reload?
thanks
Nancy
