Event schedule does not exist

  • Hi,

    In my php error log, I see many lines like below:

    [27-Jun-2023 05:06:25 UTC] Cron reschedule event error for hook: job_manager_usage_tracking_send_usage_data, Error code: invalid_schedule, Error message: Event schedule does not exist., Data: {"schedule":"job_manager_usage_tracking_two_weeks","args":[],"interval":1296000}

    I asked the server manager, he said “This is due to a hook called “action_scheduler” does not exist in wordpress core at all. Troubleshooting cron job errors are outside our scope of support”.

    So, how to fix such an error?

  • HI!

    If I am not wrong, this message comes from the WP Job Manager plugin. I suggest opening a thread there:

    Yes, you are correct. However, there are other similar enties, like below:

    [27-Jun-2023 14:43:24 UTC] Cron reschedule event error for hook: ngg_delete_expired_transients, Error code: invalid_schedule, Error message: Event schedule does not exist., Data: {"schedule":"ngg_custom","args":[],"interval":900}

    This cron task should come from another plugin WP Rocket. As the issue is not specific to one plugin WP Job Manager. So I choose to post it here instead of a plugin-specifc forum.

    Hi @chcw

    The error mentions a scheduled cron event that was never executed. The causes of it, there could be missing PHP files, a permalink changes due to migration.

    Although it’s completely safe to ignore this message, you can try to manage your corn jobs with the WP Control plugin:
    https://www.ads-software.com/plugins/wp-crontrol/

    Look for corn jobs coming from ngg_delete_expired_transients and job_manager_usage_tracking_send_usage_data and delete them.

    Cheers,
