Bugs in forum software
From Knoppix Documentation Wiki
There seems to be a bug left in this forum software (or, more likely, the setup of it), I created a forum thread about the problem: http://www.knoppix.net/forum/viewtopic.php?t=22370
In short, I got an error message when updating any page of this wiki, but the changes seem to be active anyway, causing quite a bit of confusion on my side.
