Aaaaaaaaaaaaaaaand I think I fixed it.
I ran
rm -rf /var/lib/dokuwiki/lib/plugins/docimporter
then reloaded my main site, and it works.
So the question then becomes "what did I do wrong installing docimporter?"
And, on a related note (sorry for doubling up topics) is there a better/recommended way to convert MS Word knowledge-base files to DokuWiki articles? I know TIMTOWTDI, Perl philosophy and all that, but is there an agreed-upon best/most stable?
Thanks again.
