Changes Not Applying

I have been trying to get rid of a page that once added has thrown off the layout of my home page. I have, in wordpress editor, been able to delete the page and navigation successfully however when viewing the website from some computers that page does not seemed to be deleted. I thought there may have just been a time delay on the posting of changes however I have had this problem for the past three days. Any help is apprieciated, thank you.
