Invalid Arguement Error for Users

[meffoos]

I am starting to build a small following base at my website and I am noticing that everytime a new member joins my site, I receieve an error code above the user name...not sure what it means or how to fix it.

I have a Wordpress theme base website.

Here is the error code.

Warning: Invalid argument supplied for foreach() in /freephotoshopprojects.com/wp-content/plugins/s2member/includes/functions/users-list.inc.php on line 90

It just started showing up recently. I would really appreciate any and all suggestions. Thanks!

It appears to be related to the latest WordPress release: 3.1. I just upgraded today and am now getting that same error.

Another thread was started for it too, so I suggest you follow it to see how it may get solved.
