I am currently using Wordpress as our main webpage. I modified one of the pages so I can use them for other things such as a Contact page, guestbook, etc. without having the sidebar items that Wordpress uses. Now the pages look fine in Internet Explorer but they are messed up in Firefox. Can anyone let me know what I need to change/fix to get these pages working in Firefox?
