CB Subs - testing dummy payment gateway - gets 403

Tried all that - no change! Will you take a look?

I saw in another post something about an issue with Gantry. We are using Gantry, is there a current problem with Gantry and CB Subs? If so, is there a solution?

While doing this testing I came across the fact that the user gets access to the restricted material when he has ordered but not paid for the subscription. Is there a setting to prevent this, until paid?

Possibly, disable Gantry then switch to default Joomla template and see if issues persists.

Yes, edit your offline gateway and set it to require payment before becoming active
