PHP warning with fix ( $url[“path’] )

Hi, for a while this plugin gives a PHP warning on PHP 8.1. The problem is in the file cp-multi-view-calendar/classes/cp-base-class.inc.php.

In the variable there is only a key for path if the website runs in a subdirectory like domain.com/directory/. Running the website from the document root like domain.com/ will cause the key for path to not exist and emit a warning.

These changes should fix the warning:
In the method get_site_url
Change

    $url = parse_url($url);
    return rtrim(@$url["path"],"/");

To

        $url = parse_url($url);
        if ( isset( $url["path"] ) ) {
            return rtrim(@$url["path"],"/");
        } else {
            return "/";
        }

In the method get_FULL_site_url
Change

    $url = parse_url($url);
    $url = rtrim($url["path"],"/");

To

    $url = parse_url($url);
    if ( isset( $url["path"] ) ) {
        $url = rtrim($url["path"],"/");
    } else {
        $url = "/";
    }
