Symptoms
New version of a payment plugin was installed on Billing Application node. After that even an administrative user (the one with role "Full access") cannot open some tabs (Home and System > Setting > Payments Processing tabs in case of updated payment plugin) and can see a message in Billing Control Panel regarding absent rights:
System Error
Error Code: 0xb390bec5
No access rights granted to method
Cause
Billing was not configured after new RPM installation. Some method of the payment plugin is called by the system but a record about it is missing in "Method" and/or "MethodToPrivilege" database tables.
Resolution
Run pa_updates_installer with parameter --configure to start billing database configuration process:
# pa_updates_installer --configure
Note that service pba would be stopped to perform the necessary operations and automatically started when the configuration is over.
