Upgrade to 1.85 is complete.
I also exported the tables for lists and followups in MySQL, then reimported them, but it didn't work. Then I tried switching from SMTP to PHP Mail, but that didn't help either. Also...
Sending an email (not a followup, a standard mailing) works fine.
Previewing an email doesn't work, the subject and message are blank.
Previewing a followup doesn't work, the subject and message are blank.
I turned off dailymail a couple days ago because I received the blank followups, and I hesitate to turn it back on for a test because I don't want to send any blank followups. If we can get the preview working, I'll delete the followups from the database (I have a backup) and run another test.
