Short description of error
Clicking the Documentation button, in an Addon's description in User Preferences | Addons, fails. Instead of linking to documentation, it links to a wiki page that reads "There is currently no text in this page. You can search for this page title in other pages, or search the related logs, but you do not have permission to create this page. "
(I tested the first 12 addons listed today. All of their documentation buttons fail to link to documentation.)
Exact steps for others to reproduce the error
With *any* blend file open:
Go to User Preferences | Addons.
Expand the view of any addon.
Click the Documentation button.
See the wrong wiki web page load.
