Fatal Error when activating plugin

Hi!

Thanks for a simple but great plugin!

Recently I’m getting this message on new installations.

Do you know why and if it is because of the plugin, will there be a fix?

Plugin could not be activated because it triggered a fatal error.

Fatal error: Cannot use $this as parameter in /customers/b/8/3/example.com/httpd.www/wp-content/plugins/simple-automatic-updates/sau-automatic-mode.class.php on line 146

Thanks in advance!

Best regards Viche
