Re: Site breadcrumbs not working?
Just to be clear, are you talking about the breadcrumbs option that can be activated on the Site Identity admin page, and by articles do you mean wiki pages (different from articles in Articles feature)? If so, in my experience this is fairly useless.
I think the problem is that wikis in general don't have a set hierarchy of pages, so a conventional breadcrumbs trail (indicating the way back through the "branches" to the "trunk") doesn't really apply. There is no consistent trail to any given wiki page (no "deep") since it's a flat hierarchy. (The exception being pages in a structure, which do have a consistent set of relationships set by the admin. Structure breadcrumbs do function the expected way.)
Tiki also doesn't have a set hierarchy for features, etc., so the Site Identity breadcrumbs are pretty useless outside of the wiki pages as well. A breadcrumbs trail with two links isn't really very helpful.
Tiki does have a breadcrumbs module, that lists visited wiki pages, most-recent first. This also works OK in my experience, but is in a side column rather than at the page top, so might not be noticed/recognized by users.
Does this help?
