Wild Thumper Controller ...No forward drive on right wheels

Hi I have a Wild Thumper Controller with no forward drive on right wheels, was working ok for about 5 minutes then got this fault. Left side drives backwards and forwards but right side only drives backwards. Would be very grateful for any help.

Any luck getting it to work again? Without more information, it sounds like part of the driver chip fried. Can you swap the connections to the motors and see if you have the same thing (confirming it’s the side of the motor controller as opposed to the motor?). You can also verify your code again and send full speed forward and full speed backward to each side. Re-confirm you assigned the correct pins in the code: two for PWM, and two for motor direction. Post your (simplified) code if needed.
