I created the Coulisses page in order to keep the main page tidy while being able to post “secondary” material elsewhere in the site.
Unfortunately I was not able to find how to choose where my posts appear.
Apparently I need to use something called “WP_Query” and “Get_posts”.
I am however very bad with coding. 😦
I guess I will have to request some help from HaQadosch.
Sorry for the mess in the meantime.
