I recently had to upgrade this site to PHP 8.x. The Corpo theme I use is pretty old (the link to the developers website doesn’t work anymore). When upgrading I got this:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function WP_Widget::__construct(), 0 passed in /some-path/janscholtyssek.dk/httpd.www/wp-includes/class-wp-widget-factory.php on line 61 and at least 2 expected in /some-path/janscholtyssek.dk/httpd.www/wp-includes/class-wp-widget.php:162

The solution was to edit the files in /some-path/janscholtyssek.dk/httpd.www/wp-content/themes/corpo/functions/widgets and replacing the named constructor, e.g.

function corpo_contact_widget() {
...
$this->WP_Widget( 'corpo_contact_widget', __('Corpo: Contact widget', 'corpo'), $widget_ops, $control_ops );
}

with this:

function __construct() {
...
parent::__construct( 'corpo_contact_widget', __('Corpo: Contact widget', 'corpo'), $widget_ops, $control_ops );
}
