Hi Sky – this system isn’t telling me when I have responses so I had no idea you’d written me back. Apologies. I’m afraid I’m only working very part time for the people with the issue and they are not in a position to deploy a dev site – I will definitely let them know that they should look into it. For now I’ve hidden the error and if I can get them to stage the site I’ll circle back with you and see if we can find the source of the problem. Thanks so much.
