Here are the errors I am getting:

Warning: Undefined property: attributes in ./lib/tree.php on line 529
Warning: Undefined property: delimiter in ./lib/tree.php on line 529
Warning: Undefined offset: 1 in ./lib/tree.php on line 168

The above just keeps repeating on my browser screen, until it times out.
