Hello,
Is your cbpaidsubsbot Joomla plugin installed and published ?
Did you see chapter 11 of CB Paid Subscriptions Manual (pages 469-480), available in our Downloads menu ? It includes a few examples.
To control tab edit separately, you need to choosed the "detailed controls" in the "Integrations" / "CBSubs Fields Tabs protect" tab of the tab settings:
A. Availability depending on profile Owner's subscriptions
2) For Profile owner himself:
Still Available for Profile Owner himself
Owner plans controlling tab editable (none means not controlled) <----
