I seem to have broken sending mail trying to remove the notification section from the template. I duplicated and deleted the Notification Email section under Technical/Email/Templates thinking that would simply ignore and remove it. However now I get the following error when sending:
"File "C:\Program Files (x86)\Odoo 9.0-20160827\server\openerp\addons\base\ir\ir_model.py", line 974, in xmlid_lookupValueError: External ID not found in the system: mail.mail_template_data_notification_email_default"
I have sifted through everything trying to restore this and update its location but no luck. Any help on resolving this is greatly appreciated.
