Has anyone else noticed, and is this a WP 2.7 problem? In the invitation code tracking dashboard widget, I get the following warning:
First argument should be an array in [...]/wp-content/plugins/register-plus/dash_widget.php on line 24
It's not a stopper to actually using the plugin, as I still see the stats, but I hate seeing even the warnings. For what it's worth, I'm getting it on all my blogs, on different servers.
