PHP Warning: include(/var/www/html/....../lib/Cake/Error/ErrorHandler.php): failed to open stream Error

I encountered this error when trying to load my webpage.

The path that was showed on the error message was,

PHP Warning: include(/var/www/html/http://ift.tt/1XO5L0o): failed to open stream:

It wasn't able to locate the Cake library directory as the path should be "/var/www/html/http://ift.tt/1T8AeqY..." instead.

Any idea how I can fix this?

The error was pointing me to line 540 of the Core/App.php file which is,

if ($file = self::_mapped($className, $plugin)) {
        return include $file;   <<---- LINE 540
}
$paths = self::path($package, $plugin);

Thanks!
