I encounter 3 problems when the plugin 9Mail is activated

Hello !

I encounter 3 problems when the plugin 9Mail is activated :

1. a PHP error (see below)
2. confusing template when used with the plugin “Restrict Content pro”
3. when 9Mail is activated automated publication doesn’t work

Frontend :

1. no problem noticed

Backend :

1. the plugin works and send email with the template
2. some mails doesn’t hesitate from the 9mail template, seems related to Restrict Content Pro
3. The plugin SchedulePress Pro – Formerly Known as WP Scheduled Posts Pro) fail to publish the scheduled CPT

Can you help me ?
