I uploaded and activated the Product Theme on my wife's single install (i.e. non-mu, non-network) model wear ecommerce site. She rolled up her sleeves and started reconstructing it from her prior 2010 theme. For some reason, the menu is stuck and no matter she or I do in appearance>menu, it doesn't translate to the front end - it just stays stuck on a particular menu. We tried deactivating all other plugins. We couldn't find any directly applicable forum posts or trouble shooting instructions. Any ideas?
