Problem after update

[warren]

Hello,
I m sorry to disturb all of you.
I follow this tutorial : http://www.typolight.org/manual-update.html
But i have one error : Fatal error: Class 'Model' not found in /XXX/system/libraries/User.php on line 38
I valide all config in /typolight/install.php

Have you an idea ?
Thanks in advance.

Best regards,
warren

Try using the system check tool to see if you are missing any files: http://www.typolight.org/configuring...tem-check-tool
