CBSubs Options console error

First try unpublishing CBSubs Options, clear Joomla cache, then retry. If registration goes through then it's CBSubs Options. If it doesn't repeat this process except unpublish CB Paid Subscriptions itself. Seams like you may have a plan marked exclusive and is hidden for whatever reason and that's trigger validation errors.

Tried all, issue persists.

You should not be seeing an unauthorized error. That suggests the plugin isn't accessible when attempting to load in the plan options. Please be sure both CBSubs and CBSubs Options in CB > Plugin Management are marked as Public access.

Checked that CBSubs Options is Public. As far as CBSubs, I don't see any plugin named CBSubs. I have 19 CBSubs plugins but none is named just CBSubs.
 
 

EDIT: Finally the cause was coming from the parent plan as it was non-exclusive. Turning it to exclusive the registration process goes fine. I don't understand why though. I am sure I had checked these plans in the past and they were working fine. I don;t know what to say... I will evaluate  them again.
On the other hand the issue with the fontawsome is not fixed...

In order to register without a subscription you need to be sure within CBSubs > Settings > Global that you've set CBSubs to allow free registrations without subscriptions otherwise it will require one regardless of plans being marked exclusive or not. So that option either needs to be enabled or you need to mark your parent plans as exclusive and offer a free plan for non-subscribes (e.g. like what we've done here at Joomlapolis). If free registration without subscriptions is already enabled please PM backend super user login credentials and will take a look.

You'll need to reply to your existing topic regarding that with further details after doing the suggestions steps (switching to default Joomla template).

Yes, the setting "allow free registration" is enabled, and free registration appears to be functioning properly. Below is the structure I have, and I am trying to understand the logic regarding plan interaction. Users can register for P0 or P1 without issues. Access to P2 and P3 is restricted during registration and is conditionally available for upgrade. My goal is to be able to have transitions like moving from P0C3 to P1C2. In general I need to be able to upgrade or downgrade among Child plans associated with different Parent plans. Note that a Parent Plan can not function without the selection of a Child Plan. The problem appears with the non-exclusive Parent Plans for some reason at registration. Is there a flaw in the structure I am implementing? So before uploading it from my local to a remote server for you to have a look, I need to be sure that all is properly done.

Sorry, I forgot I had opened another topic. Answered there...

REGISTRATION ONLY (NO UPGRADE TO THIS FROM OTHER PLANS) OR DOWNGRADE TO P0
P4 -> -> Exclusive -> Lifetime-> Free

That plan would be your problem. It's marked exclusive and none of your other parent plans are. That plan is mandatory.

Exclusive = Mandatory = Required

So you either need to make all your parent plans Exclusive or Non-Exclusive and use conditions to limit access. In your case since you seam to want to allow upgrade/downgrade from/to parent plans they should all be marked Exclusive.

As a first step I made the PPs non-exclusive. Yes the issue seems to be solved.

In your case since you seam to want to allow upgrade/downgrade from/to parent plans they should all be marked Exclusive.

The problem with having all PPs exclusive is that when a user wants to upgrade to another PP->CP, he has to unsubscribe from his current Plans and there is no prorating. Having the PPs non-exclusive, the user can keep both PPs and their respected Child plans simultaneously. Am I wrong?
Or there is another way to have prorating when upgrading to another PP->CP ?

Prorating is per plan. So plans you want to allow prorating simply enable that. As for upgrading by default upgrades are only to plans more expensive, but you can change upgrading to ignore pricing under the workflows tab by setting "Propose plan for upgrades only if it is more expensive" to "No". That should allow them to upgrade/downgrade as needed.
