Wiki

Hello

I reproduced what you say but with different results. my page name did change on the update wiki page but not in the real wiki

let me explain.

Page name is not a christening of the wiki.
it says
If you want the first wiki page name to be something other than the wiki name, you can specify it here. This name will become the first page of the wiki for every created instance of this wiki.(did you create permanent pages in that wiki???)
If you leave this field blank, the initial page name will be the wiki name, unless you select a page in the 'initial page' field.

Now What i see is that you have NO INITIAL PAGE either.
Try having a few pages in that wiki and then try again to do this. note what name appears on top of wiki pages.

I agree that when you click on update wiki, the page name appears to be same as that of wiki, but even after i re-started the wiki after saving, my page names remained same on the wiki page.
May be because i have a specific initial page.

But yes, inability to edit the page name is annoying.
