Hi,
I have added custom code as instructions:
remove_action( 'babe_order_status_update_before_order_actions', array( 'BABE_Emails', 'send_standard_emails' ), 10, 5);
I also checked the cronjob but this action is not running.
I think it is their responsibility to assist you with this problem, they sell this plugin for a rather high price but it seems that they do not support their customers enthusiastically.
