I had problems with upgrade when I copied our wiki from an old machine (debian sarge; debian package version of usemod-wiki: 1.0-6) to a new one (debian Debian 6.0 "squeeze"; debian package version of usemod-wiki: 1.0-10): an WikiBugs/BadPageVersion
error was reported.
After some research I found UseModWiki/NewFeatures
. In chapter "Better compatibility with 8-bit characters"
action is mentioned. I applied this action to my new wiki. That helped me to solve the WikiBugs/BadPageVersion
