Unable to edit Confluence Page - Uncaught TypeError: Cannot read property 'top' of undefined

[Adrian Cloghesy]

I have one page that we can not edit anymore. -Running Confluence 7.4.7

The page is very big, I tried to copy it to another page but failed. I tried to edit it from every different browser I have access to without any luck.

When we click edit it pauses for a moment then loads up completely blank.

The error that Chrome gives me is the following.

Error on load - Failed to load resource: the server responded with a status of 404 ()
