The problem was finally easy to be fixed. As stated above, the problem is in cluster_view.php, line34. Just going to line 26 and substituting
$context_metrics = "";
with
$context_metrics = array();
fixes the whole problem! The solution was found at https://github.com/ganglia/ganglia-web/issues/324.
