How It Affects Your App
MySQL 1544 ER_EVENT_EXEC_TIME_IN_THE_PAST error occurs when an event is scheduled to execute in the past. This error can prevent the application from running properly as the event will not be executed. This can lead to unexpected results and can cause the application to malfunction. It can also lead to data loss or corruption if the event was scheduled to perform an important task.

8. Check the MySQL query cache to see if any of them are corrupted:
