MJ – occasional meaning 1 person, maybe 2 had problems. The first person enabled cookies again and unfortunately I couldn’t track down why the second person couldn’t post a comment.
Since I installed the cookies protection over 1,600 comments have been left on my site so it works for most people and it’s stopped tens of thousands of spam comments. I’m really sorry to see you go, but it doesn’t affect feed readers.
