Update:

The problem was that since my website is in Hebrew language, I named my plans in Hebrew (UTF-8).

The PayPal account language encoding default does not support UTF-8 so it had a MISMATCH in the name plans and could not confirm and activate it.

I went to PayPal > Profile > Selling Preferences > Language Encoding and changed all to UTF-8.

Problem solved.

I Recommend to add a note on this, maybe in your documentation (which is amazing BTW...), for NON-ENGLISH websites to pay attention on how they name their plans.

Thank You!

Well, celebration were a bit too early...

->

After another test we made today:

PayPal SANDBOX: All 100% OK

PayPal LIVE: Not OK.

As before, payment is actually being made.
1. The CBSubs system keeps blocking the user from accessing that plan.
2. The user is having a "Waiting Payment" for that plan on his account.
3. On Paid Subscriptions > Payments there is NO INDICATION for any payment.

The ONLY thing I changed was the PayPal details for the account, from Sandbox to Live.
I checked it carefully, and did this test 3 times with the same results.

I really don't know what is going on.

Any chance to send you PM with access details?
