AUTH201: Insufficient role
What this means
Your account does not have permission to perform this action.
Ask a store administrator to grant the required POS capability, then try again.
Your data
No order or product data is affected. If this persists, ask your store administrator.
Troubleshoot
At the till — for the cashier: note which action was refused (the log entry records it) and pass that to your administrator.
On the store — for the site administrator: review the account's role — POS cashiers need the POS capabilities WCPOS registers, and role-editing plugins can strip them.
Back at the till: once the role is corrected, sign out and back in, then try again.
