Hmm, strange, I really do have PH running on mine, it's been about 14 hours and still flashing. Try the following to see what happens.
First startup the controller with the circuits plugged in and open the Arduino ID serial monitor on the controller. Once you start seeing lines of code scroll that say PH, ORP, DO and EC all with 0.0 then plug in your circuits and see what happens. If your lights are blue on the circuits they are in I2C mode and should flash every couple seconds. If it locks up can you try only your PH circuit?
