I followed the instructions here: wcdocs.woothemes.com/user-guide/localization/ to put my WooCommerce in Italian, and it screwed up my categories. If I click on 'shop', it brings up my categories, but when I click on the categories it gives a 'page not found' message. Also, if I click on a category in my dropdown menu, it doesn't bring me to the category but a random product within the category.
I'm not running WPML because I only need it to be on one language (Italian), all I did (if I remember correctly) was follow the instructions in the link above.
How do I fix it so my categories work? Do I need to recreate all of my categories? I hate to do that because I don't want to have to come up with an alternative name for everything.
Sorry I'm not providing a link, I have an 'under construction' sign up so there wouldn't be anything you can see
