Safari Issues

[Michael Doig]

Up until this point every site I have worked on that looked good in Firefox looked good in Safari. I recently made some changes to a site and it looks fine in Firefox, but wacky in Safari. If I continually reload the site it will display properly in Safari. Several of the pages such as the menu page and the catering page are using the same css divs and one page drops a div, but the other doesn't very weird stuff. It is a wordpress site so I am really lost about why the same header would be different on different pages.
