Success! Everything's now working again.
I title yesterday "As My Mobile Lay Dying".
Anyway, I had tried to edit the noms yesterday on the mobile before posting, even though it was going to be a laborious process, but it wouldn't give me a scroll bar on the post box I was editing so I couldn't scroll down to the necessary text.
I'll update noms now. Still open for about eight more hours.
ETA - HomeInMyShoes, you actually thirded The Iceman Cometh.
