Logging ======= Errors on the Group-Office server will be logged trough PHP. Normally you can find errors in the webserver error log. When using apache this is:: /var/log/apache2/error.log ActiveSync is implemented with the Z-push library. This will log errors to:: /log/z-push-error.log Debugging --------- When $config['debug'] = true; is set in :ref:`config.php `. Then debug info will be logged into:: /log/debug.log Z-Push `````` Either when $config['debug'] = true; or $config['zpush2_loglevel'] = 32; is set in :ref:`config.php `. Then additional ActiveSync information will be logged into:: /log/z-push.log If you want to debug specific users you can set:: $config['zpush2_special_log_users'] = ['username1', 'username2'];
