Switching to FastCGI for Hiki turned out to be no viable option, since the Apache logs still shows errors, now from mod_fastcgi. So, the wiki is disabled, until I have found and installed something I like. At work we use MediaWiki, so perhaps I’ll just run that. Other wiki’s seem too immature, lack proper security-features, run their own webserver, or have just too many features that it’s not a wiki anymore.
My Hiki installation is here. But sometimes when I go there, I get a server-error as response. Like: site cannot be found, or something. Refreshing it sometimes works, but sometimes I need to refresh a couple of times to finally get the wiki page. It’s not the server or the disk being busy, since other pages work fine. My best guess was that it would be the Apache -> Ruby integration. Where else then the Apache-logs to look for that? And the errorlog proves I’m right: a big stackdump or whatever it is with references to mod_ruby. So I’ll have to either switch to FastCGI or have to look for a non-Ruby wiki (of which there are so many that you’d think that everybody on this planet wrote one).
