I just looked a little closer at the database and it appears that I need to delete select rows from the wp_fep_messages, wp_fep_participants, and wp_fep_messagedata tables. Since I updated on 2/27/2020 I’m guessing that I need to delete all data from before 2/27/2020. Am I correct?
How do I remove those messages? What table are they in? I’m very comfortable working in the database myself . Are the previous messages in the wp_posts or wp_postmeta table? What would be the SQL criteria for identifying those old messages? I can delete them myself if I know the SQL criteria
