Recently upgraded to WP 6.1 and this plugin bbPress Advanced Statistics gives deprecation warnings when I have debug mode enabled:

The official website for the plugin seems dead now.

The warnings:

Deprecated: Required parameter $version follows optional parameter $file in /customers/e/9/c/publictalksoftware.co.uk/httpd.www/wp-content/plugins/bbpress-improved-statistics-users-online/includes/core/class.utils.php on line 25

One example:

    public function __construct ( $file = '', $version ) {
        
        $this->init();

    } // End __construct ()

I understand what it means, and I see that the parameter is ot used in the function. Dos that mean we just delete the parameter?

Another example:

    public static function instance ( $file = '', $version ) {
        if ( is_null( self::$_instance ) ) {
                self::$_instance = new self( $file, $version );
        }
        return self::$_instance;
    } // End instance ()

Problem here is that the version value is being used.

Advice appreciated.

I noticed for another plug-in with similar issue it said:

PHP8.0 has deprecated the use of optional parameters before required parameters.
When running this plugin on a website that runs PHP8.0 or higher, there is constant stream of errors about this.

I confirm I am using PHP8.

I think easiest is to drop the defaultness of first parameter in function declaration.

I don’t have a copy of this plugin, but given that calling these functions does by necessity involve specifying all the variables, I’d suggest you simply take out the='' in the function where it is erroring.

so in your example change

public function __construct ( $file = '', $version ) {

to

public function __construct ( $file, $version ) {

and do this for all the ones erroring
