Hi @tpodgro
Is it possible that you are calling this code outside the posts() loop?
If so, you will need to assign a post id as the second parameter on the have_rows() function like so:
$post_id = '123';
if( have_rows('elementalaune',$post_id) ):
while ( have_rows('elementalaune',$post_id) ) : the_row();
get_sub_field('image');
get_sub_field('texte');
endwhile;
else :
echo "Nothing here";
endif;
