Pages not saving when editing in Upfront

Hi guys, I am trying to change my 'archive' pages. I am editing in Upfront but when I press save it says it is saving but when I try to navigate away from the page it says there are elements on the page that haven't been saved. No matter what I do I cannot save the changes I have made. Can you please help me? I'm trying to change http://www.melaniemay.com/author/melanie
