So it isn't a stylesheet issue.
If I want to diagnose the problem...
- I'll delete all alerts as you described in another thread.
- I enable system messaging (since I've turned it off.)
- This table should now be empty - right?
- Then as I assign the new certifications and learning plans I'll keep checking this table to see that they all default.
Otherwise I delete the alerts and leave system messaging off for now--and trust that when I launch the site, this won't happen again.
