smush_check_for_conflicts is delayed (warning in Site Health from WordPress)

Hi @claudiop58,

Based on the error shown it seems that the wasn’t run on time which caused the report.
Cron jobs depend on the site visitors so if the site is new and doesn’t have many visits it’s possible that the cron job didn’t get a trigger to run on set time.
This shouldn’t cause any issues on your site and the cron job will simply run later on, but you can consider replacing WP Cron with Real Cron Job if you wish to resolve this.

Actually I used Smush to optimise the size of my images, but in my understanding it was not “working in background” all the time. But maybe I’m wrong.

Let me elaborate a bit how Smush optimization works which should help explaining the above question.

When you activate Smush you can run Bulk Smush from Smush panel, this will optimize your existing images in bulk of 50 images per run. There’s no limit on how many images you can optimize but you will need to start the process again after 50 images are optimized, this limit is only set in free version, Pro version can optimize all images in one run but both require Smush tab to be opened during the process.

In Bulk Smush panel you will also see “Automatically compress my images on upload” option.
When this option is enabled then your newly optimized images will get optimized as they are uploaded to your site, so after you finish with Bulk Smush of your existing images then new ones will get auto-optimized on upload.

Hope this clears things up.

Cheers,
Predrag

Hi Predrag ( @wpmudev-support1 )

Thanks a lot, your answer does clarify a lot.

I would say, it is exactly as you supposed, the site is new and I am almost the only visitor ?? or so it seems…

If you could be so kind to shortly elaborate on what is WP Cron… because if it is a Plugin, I do not have it. Or, most probably, it is some kind of internal WP process?

Anyway I understand I can ignore the warning, and that’s it! Since I am new to website creation and maintenance, I try to understand everything.

Thanks again
Regards
Claudio

Hello Claudio

Cron jobs are scheduled jobs that are used by WP, themes or plugins.
These are needed for functionalities and checks that need to be happening in intervals.
For example, a plugin might need to check for updates in a DB every 1 hour. This can be done with a cron job.
You can see all scheduled events of your site through the handy plugin WP Crontrol:

even though most of the times there is no need to edit or manually trigger them.

Warm regards,
Dimitris

Thanks a lot Dimitris
Best regards
Claudio
