@ethanchoi thanks. The error startet after updating to 1.5.9.5
so i couldn’t solve it until now.
I’ve tried your link as well (https://example.com/wp-admin/tools.php?page=action-scheduler)
But I receive:
“Action Scheduler migration in progress. The list of scheduled actions may be incomplete.”
“It appears one or more database tables were missing. Attempting to re-create the missing table(s).”
Thanks
