Hi @hypocrite,

Please try activating the "Asynchronous" mode shown in the manual page:

Thanks. Found it.

I was able to get the cron jobs running.

But one post keeps getting an error:
Could not lock post. It may already be processed.

It happens daily. What can I do to remove this?

Hi @hypocrite

That error occurs when any scheduled job is already started and for some reason has been not finished when you try to execute it again. Could you please go to your Scheduled jobs list (Dashboard > System > Scheduler) and look how many "Send notifications for..." jobs have you pending or in "error" status?

Sharing a screenshot could be useful as well.

Regards !

It's only that one post that keeps getting errors. I have tried deleting the task but it keeps creating it again and then it errors again.

Here's a screenshot:

Now there are two but I have tried deleting them.

Any idea for this?

I am still getting the cron error for this one post.
