I installed the plugin at a fresh WP 3.4.2 instance w/o any other plugins and gave it a try. Seems there are issues and it doesn't work as it should.
1. I have set expiration frequency to 5 minutes and posts are supposed to go "private" after expiration and to be assigned to category "expired". Does not work - once the expiration time is reached - nothing happens - posts stay published as they were. I tried to change the expiration frequency to different intervals, also "draft" instead of "private" - no matter - does not work.
2. I've set options to notify admin/author upon expiration via email. Everytime I save settings, I receive email notifications over and over for posts that were supposed to expire (but they didn't). Even I delete those posts permanently (from trash), notifications keep on coming each time I save plugin's settings - no matter I change something in settings or not. I even deactivated and deleted the plugin and installed it one more time. It remembers deleted posts' notifications anyway - each time I save options - emails keep on coming.
3. I also noticed that if I didn't use the email notification initially, and then turned it on, it also applied to previous posts that never used it. And notifications come once options saved...
Is there any way to fix it?
