1 The "ikwiki.cgi?page=index&do=edit" function has a problem
2 when running with [[!debpkg thttpd]] or [[!debpkg mini-httpd]]:
3 for some reason the headers ikiwiki outputs are transmitted
4 as the page content. Surprisingly, the "do=prefs" function
7 Here is what it looks like in iceweasel:
9 Set-Cookie: ikiwiki_session_apnkit=99dad8d796bc6c819523649ef25ea447; path=/

18 Ikiwiki runs fine with [[!debpkg boa]].
22 It doesn't work for signin either.
23 What is the reason for these "header => 1" in FormBuilder initialisations?
24 Why do they appear two times with conflicting values in the very same hashes?

69 Marking [[done]] since it's not really an ikiwiki bug. --[[Joey]]
73 I'm using boa and getting some odd behaviour if I don't set the `umask`
74 option in the config file. Editing a page through the web interface and
75 hitting "Save Page" regenerates the `index.html` file with no world-read
76 permissions. As a result, the server serves a "403 - Forbidden" error page
77 instead of the page I was expecting to return to.
79 There are only two ways I found to work around this: adding a `umask 022`
80 option to the config file, or re-compiling the wiki from the command line
81 using `ikiwiki --setup`. Setting up a git back-end and re-running `ikiwiki
82 --setup` from inside a hook had no effect; it needed to be at the terminal.

95 (I'm new to wiki etiquette - would it be more polite to leave these details
