I have a WordPress blog hosted by Bluehost. Earlier today, I stopped receiving email comment notifications. I have not made any changes to the code in my blog and I am able to receive emails sent directly from the contact form on my site. I also spoke with Bluehost and they said they have not made any changes to my account and therefore do not know what is causing the lack of emails.
Any ideas as to what could be happening? Or what else I should ask Bluehost to look into?
