using wp-4.9.1
If I mark a single post to expire in the future, all posts are marked to expire on this same date, e.g. 2018-01-01. In this case, the post isn’t marked expired, as I stated earlier.
I set DISABLE_WP_CRON to ‘true’ in wp-settings.php and setup a cron job to run wp-cron.php every 1 minute. That seems to make no difference.
I created a new post, checking “enable post expiration” with a default +1 month date. When I publish this new post all posts are then given this new expiration date of +1 month – 2018-02-02.
I created a new post, not checking “enable post expiration”. When I publish this new post, all posts are given an expiry date of “never”, except for 1. Perhaps this one had a date in the past.
It seems that the post expiration date is getting updated globally, rather than the to the one that should be updated.
