I have a strange problem with editing any page after its first SVN commit.
I'm not sure whether it's my ikiwiki backport bug or my misunderstanding
how ikiwiki works.
Assume that I have Foo page with any content and I want to put there link
to Bar page and next create the page. I do following steps:
1. Click Edit link on Foo page
2. Put the link to Bar page there and commit it by clicking "Save Page"
button
The Bar page is rendered correctly and now I can see ?Bar link. The URL
in the address bar of my browser is
http://my.host.com/wiki/foo.html?updated
3. Click ?Bar link
Now I can see textarea for editing of page. It's empty, of course.
The page doesn't exists in my SVN repo yet and my Apache server knows
noting about it:
$ find /my/ikiwiki/src/dir/ -type f -name bar.mdwn
$ find /my/ikiwiki/dst/dir/ -type f -name bar.html
4. Add some initial content and click "Save Page" button
to commit changes
The Foo page also is rendered correctly and now I can see what I wrote.
The URL in the address bar of my browser is
http://my.host.com/wiki/bar.html?updated
The page was added to the SVN repo and my Apache is able to serve it now:
$ find /my/ikiwiki/src/dir/ -type f -name bar.mdwn
/my/ikiwiki/src/dir/bar.mdwn
$ find /my/ikiwiki/dst/dir/ -type f -name bar.html
/my/ikiwiki/dst/dir/bar.html
5. Change the content of Bar page by clicking Edit link
I can't do it, because the textarea is empty again. I have to run
`ikiwiki --setup ikiwiki.setup` command by hand to rebuild the page.
Then I can edit it.
Where is my mistake?

Sorry I am not indenting for my reply (in my browser the responses are very narrow.)
I also had problem with no webpages getting generated via the CGI unless I ran ikiwiki to regen manually.
I can't find the discussion here about in the ikiwiki website though. I think it was removed and now I can't find it in the history.
My problem was caused by not having a revision system defined, so it defaulted to subversion (but I didn't have that installed).

As for your .setup file you can put it anywhere. I don't think the CGI knows where it is at because its settings are set in the "wrapper".
In my case, my setup file is in a different home and owned by a different user than the CGI or my generated website. By the way, I also don't keep my .ikiwiki private directory in my source directory by setting wikistatedir (which doesn't seem to be documented).
