Uncertain operating mode

As previously commented, this plugins do its job but also deactivate many posts where expiration date hasn’t be defined. Maybe you may need to install it on a fresh project, before adding content, if you want to use this feature and make it works as expected.

EDIT : I revised my review as this issue is now fixed, see comments below

Nevertheless, Content Expire Scheduler doesn’t respond exactly to the planning feature I looking for, as it only add a prefix to expired posts and replace “the_content()” by a custom notification.

That’s unfortunate because imo it uses the best way to integrate such a system to WordPress, adding expiration fields within the post publish/schedule box.
