Hello,
I've been getting about a 20% failure rate using CBSubs- the Log Type displays: PDT notification not authenticating at payment gateway (paypal). I searched and found topic #2374 and it seemed to indicate a bug (and yes, I checked the settings).
I'm running CBSubs v1.1.2 which this problem seems to apply to.
I know I should update but the site is complex with a RT template, Kunena, Virtuemart, uddeIm and I've been hesitant since it all works.
Q: Was this a bug and if so, was it patched in the newer releases?
