Every time I test, I get this message:
ERROR: Unable to modify Subscription.
Please contact Support for assistance.
The existing User ID is associated with an Administrator. Stopping here. Otherwise, an Administrator could lose access. Please make sure that you are NOT logged in as an Administrator while testing.
The plugin WAS working fine, and suddenly this has started to happen. I have not installed any new plugins or made any other changes.
It's annoying because my customers are also reporting this message when they sign up so they are asking for refunds.
Any ideas?
Thanks.
