Hi there sweeneysss,
To resolve the error "One or more super funds selected is inactive and can't accept payments," I'd recommend contacting the super fund directly to confirm if they've changed any of their details. Once you have the updated information, you can update the super fund details in your MYOB account to continue creating super payments. You can check this link for more information. To know more about super fund and to check if there are any contribution restrictions, you can enter the fund ABN through this link.
Best regards,
Doreen
