ParticipantI have this appearing when entering the plugin: The WordPress scheduler is not working properly: that affects the newsletter sending and other site tasks.
See possible solutionsI tried to resolve it as instructed as I have an important newsletter that has been sitting all day at 0 sent. Not sure what to do…Any help would be greatly appreciated!
Thanks!

KeymasterHi, on the Help/Scheduler page you should see the specific error: if the job is just late, you need an external trigger, as explained on this page:
The error message takes a while to disappear but you can see on the Help/Scheduler page the graph reporting a shorter interval between the scheduler activation (it should be less than 300 seconds).
If you have a cache system like CloudFlare wrongly configured (caching the calls to the wp-cron.php calls) you should ask the provider to fix it. If you share your site address I can try to check that problem.
If you have an error “job skipped”, this is a more serious issue and needs to be debugged.

ParticipantHi Stefano, yes as mentioned – I tried fixing it that way and can’t get it to work.
The site is sonoraindoorsoccer.com.Thank you!

KeymasterHi, you have Cloudflare as a cache, but it seems ok. Did you setup the scheduler external trigger using for example cron-jobs.org?
You should see on their console if the calls are going ok or not.
And what about the Help/Scheduler panel? Could you share a screenshot?December 24, 2025 at 6:44 pm #352414User
ParticipantIt’s not skipped – it just shows ‘Sending’ still and it’s been about 24 hours – hasn’t sent 1. The recommended chron external plugin didn’t do anything.

ParticipantNo idea Stefano. Not sure about anything you’re talking about actually.

ParticipantI’d really like to get this newsletter sending if possible asap. All other newsletters have sent perfectly – never an issue – what happened suddenly??

KeymasterHi, the Help/Scheduler panel reports some information about the scheduler.
Do you have some sort of optimisation plugin that is not lading the Newsletter plugin on the frontend? On Help/System we try to detect a few of those plugins.December 24, 2025 at 6:49 pm #352418Stefano
KeymasterIt’s not something about the newsletter, is something about your system… new plugins? New configurations?

ParticipantI have no idea

ParticipantThe newsletter has been working perfectly until now. I haven’t changed anything.

ParticipantHow does normally work – can you/yours diagnose/fix this??

KeymasterCould you check the Help pages? There is the Scheduler specific page and the System page as well.
