Participants Database no longer saving new entries

I had everything working. I missed setting up a Participant Record Page. It seems like once I created that, new entries stopped saving.

Now when I attempt to add a new entry using the [pdb_signup] shortcode, verbose logging shows the following, but the record is not saved to the database.

Participants_Db::process_form storing record: UPDATE *********_participants_database SET date_updated = NOW(), first_name = ‘S’, last_name = ‘T’, college_or_university = ”, email = ‘***********@gmail.com’ WHERE id = 10
