Hi @radjr
Scheduled tasks send notification after they are executed, s. pkp-lib/ScheduledTask.inc.php at ojs-stable-2_4_8 · pkp/pkp-lib · GitHub.
Depending on the setting scheduled_tasks_report_error_only in your config.inc.php, the admin would get e-mail notifications either only in the case of an error or always (i.e. also in the case of warnings or notices that everything has completed).
There are many scheduled tasks in the system:
plugins/generic/objectsForReview/xml/scheduledTasks.xml
plugins/generic/booksForReview/xml/scheduledTasks.xml
plugins/generic/usageStats/scheduledTasks.xml
plugins/generic/pln/xml/scheduledTasks.xml
plugins/importexport/datacite/scheduledTasks.xml
plugins/importexport/crossref/scheduledTasks.xml
plugins/importexport/medra/scheduledTasks.xml
registry/scheduledTasks.xml
The default scheduled task is registry/scheduledTasks.xml.
How and which scheduled tasks are activated depends on if you are using a Cron job or AcronPlugin, s. Any howto "crontab" somewhere?.
It seems that you are using the AcronPlugin and that thus all scheduled tasks are executed?
What do you then see when you follow the link i.e. in the scheduled task log file? Is there any error?
How does the setting scheduled_tasks_report_error_only in your config.inc.php look like?
What scheduled tasks do you actually need?
Best,
Bozana
