We upgraded from CSVI 5.2.1 to CSVI 6.4.3. We created a new template and everything is working except the jform command from the cronjob to have a certain range of date in the export file. We have changed the cronjob accordingly to your website.
Old cronjob (which worked for years):
/usr/local/bin/php /home/xxx/www/xxx/administrator/components/com_csvi/helper/cron.php username="USER" passwd="PW" template_id="1" jform



New cron job:
/usr/local/bin/php /home/xxx/www/xxx/administrator/components/com_csvi/helper/cron.php username="USER" passwd="PW" --key="winter" --template_id="1" jform



The new cron job generate the file but with all orders from the whole database. It looks as the jform command is not working anymore with CSVI 6. Can you give us a hint?
