ok i find the response in this post :

Template "item.html.twig" is not defined

Hi, i am new to grav and i was experimenting with the themes. I changed the theme to Notepad v1.3.0 and got the first Error “Template “category.html.twig” is not defined.” and now i can’t change back to other themes because of this bug. I also cant access any item in Notepad because it seems there are no items defined. What can i do now?

juste have to change the default home page in the site settings
