I've obviously managed to do something daft and keep on repeating the error. I've altered something on every page/tab so I can successfully use the save settings buttons; I've deleted and regenerated the API key; but still WW won't send a simple export command. I used WW experimentally and successfully a month or three ago so I can't get to grips with what I am now doing wrong. I'm admitting defeat and asking for help.
