get_terms() broken

Hi,

Im using this plugin to order the taxonomies of my CPT, but when I enable the plugin the get_terms() function stops returning the taxonomies and returns an empty array instead. If I disable the plugin all goes back to normal and it prints all my taxonomies.

This is the code I use:

register_post_type(

'products',

array(

'labels' => array(

'name' => __('Productes', 'ssll'),

'singular_name' => __('Producte', 'ssll')

),

'public' => true,

'has_archive' => false, // False Si no te archive page

'menu_position' => 22,

'menu_icon' => 'dashicons-image-filter',

'supports' => array('title', 'editor', 'thumbnail'),

'rewrite' => array('with_front' => false),

)

);

register_taxonomy(

'prod-categories', // The name of the taxonomy. Name should be in slug form (must not contain capital letters or spaces).

'products', // post type name in lowercase (not slug)

array(

'hierarchical' => true,

'label' => 'Categoríes', // display name

'query_var' => true,

'show_admin_column' => true, // Display in backoffice's post_type table

'rewrite' => array(

'slug' => 'prod-category', // This controls the base slug that will display before each term

'with_front' => false // Don't display the category base before

)

)

);

I then use the following code to print the taxonomy:

$prod_tax = get_terms(array(‘taxonomy’ => ‘prod-categories’));

var_dump($prod_tax);
