I'm at a small non-profit and picked up the hat of helping operate the web page.  Today we tried to create a new page by copying and old one.  I attempted the adjust the security settings so the page could be viewed by administrators, but instead have made the page unchangeable.  Edit page button no longer appears on the page, in the page management view or any other place.  

I've checked permission settings and I have an Administrator role.

Any thoughts on how I can restore access to this page or at least delete it and start fresh would be appreciated.
