+I believe that error message indicates that the [[plugins/lockedit]]
+plugin is preventing editing. Either make the user account you're
+trying to use into a wiki admin via the `adminuser` setting:
+
+    # either or both of these
+    adminuser:
+    - yourname
+    - http://your-openid.example.com/
+
+or allow that user to edit pages by altering the `locked_pages`
+setting.
