How can I trigger fastcci to rebuild the category
trail for that file
or category?
I'll have to set up a cron job. Rebuilding the DB takes about 2-3 minutes.
How can I use the category trail in category subtrees
that have no
featured/ valued/ quality files?
The trail is displayed if the fastcci_from url parameter is set with
the pageid of a category. You could add that by hand. If you are on a
category page type 'wgArticleId' in the JavaScript console to see the
pageid of the category.
Cheers,
Daniel
