I just upgraded from 1.10.1 to 1.11.0, and it didn't work very well.
Generally, wiki works, I can search, but I can't edit any page.
If I press "Edit" on any of the pages, it wants to edit the
"Index.php"
site. Any clues?
If anyone wants to see, go to
http://wpkg.org/index.php?title=Support&action=edit (or any other
protected page in that wiki).
