WordPress MU

foreach(get_blog_list(0, 'all') as $blog)
		{
			var_dump($blog);
			echo '<br /><br />';
		}

For some reason it doesn't show blog 57. This is bizarre... any ideas?

get_blog_list(0, 'all') from wpmu-functions.php pulls "all" blogs that meet these conditions.

AND public = '1' AND archived = '0' AND mature = '0' AND spam = '0' AND deleted = '0'

A blog user can switch their "public" with the privacy selector. Dashboard-->Settings-->Privacy.
