Arduino Uno + Arduino Motor shield + Arduino WiFi shield

Hello, im having huge problems with connecting the Arduino Motor shield and the Arduino WiFi shield.. I've learnd that this happens because the WiFi shield uses the same ports (11, 12, and 13 for instance) as the motor shield. This is causing problems because at times they are activated at the same time, and this is messing with my motos (using two DC motors). Does anyone know how to deactivate the pins on the WiFi shield or can i just simply bend them (I'd rather not do this).

If anyone have any knowledge about this please share. Would be very appreciated.
