Hi @Patrik
When you select a page to act as the ‘Blogs’ archive page, the global $post object does not point to the page called Blog, instead it points to the loop of posts.
This means that ACF will load the data (via get_field) from the wrong place (not page called Blog).
To get around this, you will need to specify the Blog page ID in the get_field function.
something like:
<?php
$post_id = false;
if( is_home() )
{
$post_id = 123; // specif ID of home page
}
$use_sidebar = get_field('use_sidebar', $post_id);
$choose_sidebar = get_field('choose_sidebar', $post_id);
dynamic_sidebar($choose_sidebar);
?>
