Lay Theme Forum

Hallo dears!
i need your help: i have deinstalled all non-laytheme plugins and turned off all custom code and still: if i do new categories, they dont show up on my website. Atm i only have two categories and like a week ago i could do as many as i wanted but they just dont show up. If I erase them, they go. But not if i add new ones. its really frustrating, can someone help me out?
thank you
