Custom taxonomies not showing

I've been using a combination of MarketPress and CustomPress on Armed & Glamorous very successfully, but I've updated my theme and it seems to have broken it. My custom taxonomies (sleeve, retailer, colour etc.) are all visible on the CustomPress screens and seem to be correct, but they don't show on the product pages, and when I try to import a CSV file for new products (using ECI importer) my custom taxonomies don't seem to be registered.

I am using a child theme of Themia Lite, and I'm pretty sure that updating Themia Lite to the most recent version is what's caused the problem... any ideas what to look at /edit to fix the problem? It also seems to have lost my sidebar, even though the file and calls to that sidebar in the page template are still there.
