-The following table should be created into MySQL/MariaDB database.
-
-```
-CREATE TABLE `eventLog` (
- `id` int(11) NOT NULL AUTO_INCREMENT,
- `date` datetime NOT NULL,
- `event` varchar(512) NOT NULL,
- `error` varchar(1024) NOT NULL,
- PRIMARY KEY (`id`),
- KEY `date` (`date`)
-) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COLLATE=utf8mb3_unicode_ci COMMENT='Event scheduler error log'
-```
-
-Then adjust the *$logTable* variable to the correct schema.
