Categories do not show

Ok, I have searched but none I have seen have had this error message. here is my site https://www.desmoinesdrinks.com I can see posts if I link directly to them like https://www.desmoinesdrinks.com/tonic but if I search by category https://www.desmoinesdrinks.com/category/west it tells me no path is there. If you go to the site, “Find drink Specials” check any category, nothing works.. worked just fine a few days ago. Showed all the bars in that cat. Now nothing. Nothing has been changed at all.
