Page moves has been disabled on English wikipedia. I am not sure what exactly is broken.
When I try moving pages with a bot it gives the following error.
"WARNING: Token not found on wikipedia:en. You will not be able to edit any page."
When I try to do the same from a human account I get the following error:
"<PAGENAME1>" cannot be moved to "<PAGENAME2>", because the title "<PAGENAME2>" is protected from being created. If you feel that this move is valid, please consider requesting the move first.
My test case was
the move of [[Wikipedia:Featured picture candidates/View of Saturn from Cassini Orbiter]] to [[Wikipedia:Featured picture candidates/Saturn from Cassini Orbiter (2004-10-06).jpg]]
