I am experiencing an issue with automated scheduled task emails continuously being sent to the site admin, and I would appreciate some guidance on how to stop them.
**Background:**
We recently received a request to enable the **Reviewer Credits** plugin. After enabling it globally, several journals activated it, but only one fully configured it. Shortly after, we started receiving configuration error emails. To stop these, we disabled the plugin for all journals.
**Current Issue:**
Even though the plugin is now completely disabled, the scheduled task seems to still be running. The site administrator is receiving a lot of emails (more than 400 in 15 days) stating with:
*“Your Open Journal Systems installation automatically executed and finished this task and you can download the log file here…”*
When downloading the attached log file, it shows the following:
[2026-06-12 05:00:04] https://URL
[2026-06-12 05:00:04] [Notice] Task process started.
[2026-06-12 05:00:04] [Error] Reviewer Credits plugin not found or not enabled
[2026-06-12 05:00:04] [Notice] Task process stopped.
**System Information:**
* OJS version: 3.4.0.9
* Reviewer Credits plugin version: 3.4.1.6
* The emails are triggered automatically without any manual intervention on our end.
**Question:**
Is there a way to safely unregister this specific scheduled task so it stops running, or a way to prevent these specific error reports from being emailed to the administrator while the plugin remains disabled?
Note: We do not have a server-level cron job (crontab) active; our installation relies entirely on the Acron plugin to handle scheduled tasks.
Thank you in advance for your help!
