Hi 🙂

1. Which URL? Can you share the _full_ value of the `category previews` theme setting in your screenshot? I should be able to give you suggestions based what you have entered into that setting.

2. When you make a change to the `category previews` setting, click outside of the text field and you should see two buttons appear. Use the green one to save changes. After you save the changes, you will need to refresh any open browser tabs/windows to see the effect.

3. Assuming **Groupe privee** is a category you have already created, you need to find and use the slug for it. It will most likely be something like **group-privee**. You can confirm this by navigating to the **Groupe privee** category and looking at your browser’s address bar. For example, the #Customization > Theme category here on Mete uses **theme** as the slug:
