Aman - please can you excuse me while I grovel!
I'm in the process of migrating all my sites to a new server. This site exists on both, and I was looking on the wrong server today. I've been doing too much and my brain is scrambled.
Many apologies for wasting your time, but I have now set you up with the same login on the correct site, and tested it and it is working for me.
If you're still talking to me, and you have the time, please could you take another look?
Thanks
Ian
