I have set up a test site for development and was trying to set up a cron job based on the instructions on the Reminders set up page as shown on the screenshot below.
I did as instructed to set up the Cron Job command on my server and also set up a test reminder. The reminder was set to go at 12 midnight last night and I got the messages from the server that are shown on the screenshot attached.
Please check to see what might be causing this problem.
Thanks
