Actually with this project I wanted to test a website only with FSE, so, for once, I didn’t even make a child theme (and now I regret it a bit ^^ ). So I choosed the archive page, in appearance, and site editor pages. Then, I use the “query loop block” (sorry if these are not the right words, I don’t use WP in french, and maybe I should, haha :D) . in request type I choosed “custom”, not “default”, and then I choose my custom post, “artist”.
Thank you for your answer. What are you calling a block theme ? I call it with gutenberg, with a “short code block” but it’s like, the base of wordpress. I have no them builder or anything, no code added, just the shortcode. shouldn’t it be working ? If it’s what is called a block theme, then it’s impossible to use. Can you tell me how to do? I use WP theme, twenty twenty four (it IS a block theme, no widget anymore).
