Gentlemen, config/index.php has called interwiki.sql and produced
table wiki_interwiki as expected. OK, but why won't e.g.,
[[commons:Bla]] become a blue interwiki link instead of a red local
link? Yes I read
http://www.mediawiki.org/wiki/Help:Interwiki_linking
but feel that as I find the table already exists, I should not need to
do anything more.
