Error sending order testnet

Driving myself mad here with what I’m sure is an obvious mistake. I’m able to send an order via production but when I try sending via testnet im receiving error 2515 however I can query market data via testnet. As discussed in other threads I clicked enable SPOT & margin trading in the API page. Any suggestions for helping would be greatly appreciated.

Could you please provide the error logs?
