I've been using WP for some time without any problems. However, in the last couple of days, comment notification seems to have ceased. I have checked that it is set to send to the correct address. I have checked that the address is working. I have checked that my spam filter is not stopping the mails (I've actually switched it off whilst I fix this). I've checked all the settings I can think of, to no avail.
Does anyone have any suggestions? Thanks.
