Process log

The way of viewing the logs has changed in the various vtenext releases and is summarized as follows.
vtenext 16.09: Logs can be consulted by accessing the filesystem in the folder logs/ProcessEngine
vtenext 18.X: In Settings → Business Process Manager → ProcessManager the button 'LOG' will be available once the following script has been executed:
<?php
require_once('include/utils/VTEProperties.php');
$VP = VTEProperties::getInstance();
$VP->set('settings.process_manager.show_logs_button', 1);
The file 01.log is initially created. When the file exceeds the 5MB, the file 02.log will be created and so on.
vtenext 19.10: Logs are available in Settings → Other Settings → System Logs
