The following two classes both define their constructors twice. This isn't the end of the world but they do different things and will trip a strict standards warning. It should probably be fixed;

• turnitintool_loaderbarclass (loaderbar.php)
• turnitintool_commclass (commclass.php)

With strict standard on you get...
