Sorry for the late reply., for some reason email notifications of posts, although enabled in my settings, do not seem to be working for me.
The feed site was redirected from the main bbc site, so your comments do not make sense to me. Why would the bbc start using an old address again. I will check the https only setting but may decide not to change it.
PS it has n't happened again recently so it may have been a mistake from bbc but who knows.
