We have been in close contact with Wikia central about this. Seems they put some changes through a week or so ago that affected editing from iPads.
They informed us today that they have fixed page editing in Safari but not comments (Loading Editor still goes round and round forever). They assure us that the full fix will be in on Wednesday next week in the next build.
However, if you use Chrome on your iPad (free from the AppStore and is sooooooo much better IMO), all iPad editing features are now OK.
Oioiaussie Please do not send me gifts. Thanks in advance.
