If anybody is having issues renewing subscriptions, please let me know. When we transferred to a different subscription manager, it created a loopback bug on the renewal. Basically, some members had two different kinds of memberships at the same time and it creates a feedback loop when trying to renew. The way I fix it is to cancel the subscriptions so they can re-subscribe, which seems to fix the problem. But I won't know who has the issue unless they say something.
Sorry for the troubles. I'm not the developer of the software, so many times I'm at their mercy and try to make things work he best I can with the tools they give me.
