I can't retrieve the data

Hi I’m trying to use the plugin, but I can’t retrieve de custom field from the categories.

It shows on the edit category page but I’m trying to get it in the front-end and I’m not capable of it.

I tried the methods that tells the FAQ but it didn’t work either.

var_dump(true, get_term_by(‘slug’, ‘course’, ‘category’));
$categories = get_categories($args);
foreach($categories as $category) {
echo ‘<p>Category: term_id ) . ‘” title=”‘ . sprintf( __( “View all posts in %s” ), $category->name ) . ‘” ‘ . ‘>’ . $category->name.’ </p> ‘;
}

When I execute the var_dump shows me all the data of that category but didn’t shows me custom field, and always tell me the string is 0.
