I believe this is due to the fact that this application is built on an older version of CakePHP, which may use some deprecated features. It would be great if you (or someone else) could upgrade Cake to a new stable branch. For now, try this in your core.php, you can remove E_STRICT from the error message:
Log in to the /Config/core.php find application
Configure::write('Error', array( 'handler' => 'ErrorHandler::handleError', 'level' => E_ALL & ~E_DEPRECATED, 'trace' => true ));
replace it as
Configure::write('Error', array( 'handler' => 'ErrorHandler::handleError', 'level' => E_ALL & ~E_STRICT & ~E_DEPRECATED, 'trace' => true ));
