We're using Moodle 2.3.2.
One of our users claims that they are receiving multiple digest mails per day. I checked our settings, and saw that the digest mail is set to go out at 5:00 pm Pacific time every day. No other user has reported this issue. He has not told me whether the content of each digest is identical or if it's different.
Any thoughts, hints, ideas, etc., would be greatly appreciated.
