But you’re missing part of your database, as you can read in the repeated error.
If this is the only error, someone (or something) deleted the daystarttime column from your schedules table. Renewing and advert solves nothing there.
So while renewing may hide the issue, it’s unlikely you have the same problem.
Anyway – run this query and it should be fixed; ALTER TABLE wp_adrotate_schedule ADD daystarttime char(4) NOT NULL default '0000' AFTER spread;
