I spent a day going round in circles and then I added &sandbox=1 as suggested and this displayed new fields I'd never seen before. With mine the Live Merchant Token was incorrect. I obtained the correct one from my Square Developer Dashboard and after saving and editing again so the location was refreshed everything started working for me.

Thanks Brent

I took the plunge and did a full upgrade of the site. I then included the inner-light fix and so far so good.
