The "ikwiki.cgi?page=index&do=edit" function has a problem
|
|
when running with [[!debpkg thttpd]] or [[!debpkg mini-httpd]]:
|
|
for some reason the headers ikiwiki outputs are transmitted
|
|
as the page content. Surprisingly, the "do=prefs" function
|
|
works as expected.
|
|
|
|
Here is what it looks like in iceweasel:
|
|
|

Ikiwiki runs fine with [[!debpkg boa]].

It doesn't work for signin either.
|
|
What is the reason for these "header => 1" in FormBuilder initialisations?
|
|
Why do they appear two times with conflicting values in the very same hashes?

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

(I'm new to wiki etiquette - would it be more polite to leave these details
|
|
on the wiki, or to remove them and only leave a short summary? Thanks.
