Hi,
I’m back, sorry for the late reply.
@soumilroy Thank you for commenting. Unfortunately it seems to be a different problem in my case. I only have 18 jobs in the wp_options
table and not all are related to Post Expirator (anyway, your query is a little bit radical as it deletes all crons from the DB, not only those related to Post expirator).
@axelseaa Thank you, the specified diagnostics logs were extracted from a test with a brand new post.
The only difference with other sites in my installation is that this site is protected (Shibboleth authentication rule defined at Apache level), but removing the rule seems not to help.
I will try to disable the built-in cron and setup a new cron job, without convictions…
