Reply To: bbPress Advanced Statistics v1.5
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
