My custom widget won’t activate

Hi!

I’m following the instructions (https://siteorigin.com/docs/widgets-bundle/getting-started/creating-a-widget/) and trying to create a custom widget using the SiteOrigin framework.

I’m developing this into a theme and not as a plugin.

I have this in my functions.php :

function pr_widget_collection($folders){
    $folders[] = get_template_directory() . '/inc/widgets/';
    return $folders;
}
add_filter('siteorigin_widgets_widget_folders', 'pr_widget_collection');

which then finds my currently one and only widget file :

/*
Widget Name: Icon Link Widget
Description: Creates a stylish icon button
Author: Herman Aus
*/
class Icon_Link_Widget extends SiteOrigin_Widget { 
    function get_template_name($instance) {
        return '';
    }
    function get_style_name($instance) {
        return '';
    }
}
// Register the new widget
siteorigin_widget_register('pr-icon-link-widget', __FILE__, 'Icon_Link_Widget');

The widget shows up under Plugins -> SiteOrigin Widgets but in can be activated. If I click on activate, it shows it’s activated but if I reload the page, it’s deactive again.

Could someone help shed some light into why this is happening?
