[Plugin: Multisite Administration Tools] Invalid Argument Supplied line 72

Really great plugin. However, I am getting an error on the plugins page:

Warning: Invalid argument supplied for foreach() in /the/path/wp-content/plugins/multisite-administration-tools/multisite-administration-tools.php on line 72

Any ideas? Seems like it is probably a simple fix.
