Random blog posts

Hi support.

I want to have the blog posts to be shown randomly, so I followed your documentation and inserted this code in the functions-file:

add_filter(‘avia_blog_post_query’, ‘avia_modify_post_grid_query_rand’);

function avia_modify_post_grid_query_rand( $query ) {
$query[‘orderby’] = ‘rand’;
return $query;
}

I have cleared cache several times without luck.

It is on the frontpage of: Lederuddannelse.

Have I missed anything – please help?

Thanks :-)
