I don't know if anyone has ran into this issue but when I tried to delete a vehicle entry I just added it wouldn't let me.

I get this error
Management: Delete a vehicle
Fatal error: Uncaught Error: Call to undefined function CheckVehicleContrib() in /var/www/imcdb/delete-vehicle.php:9 Stack trace: #0 {main} thrown in /var/www/imcdb/delete-vehicle.php on line 9

I don't need the vehicle re-added, just need it gone.
