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? --[[Paweł|ptecza]] > It's not clear which Edit link you clicked in step 5.

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). > Note that that confusing default to svn has been changed.. And you're > right about how the setup file is used below, BTW. --[[Joey]] 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). --[[JeremyReed]] > Never mind about indentation, Jeremy! :) Thanks a lot you're interested in > my problem and you try to help me. > I use RCS backend and store my ikiwiki sources in SVN repo.
