If a Trash link exists, located next to the All link, you may wanted to click it to locate all the posts that you have deleted for the past 30 days.
Hover your mouse over to the title of the post that you want to delete or restore, and a sub menu of options will appear below.
Choose Restore to recover back your deleted post or choose Delete Permanently to delete the post forever.
Caution: Wordpress will empty the trash every 30 days.
