Sembra essersi risolto un problema...ora però mi dice :

[04-Jul-2011 14:57:45] PHP Warning: require_once(/model/CategoryTable.php) [function.require-once]: failed to open stream: No such file or directory in /home/nicolamo/public_html/lib/bootstrap.php on line 14


Codice PHP:
require_once('/model/'.$file);
