I have an item that I archived that is still displayed on the front panel but not displayed in the content editor. Is there any way to restore archive items?
Sitecore 6 has a separate application for storing archived items. Open Sitecore> All Applications> Archive, and you will see archived items. There is a Restore button that will do the job for you. :)
Hope this helps.
Not sure if there is a way to restore archived items in Sitecore 6, but I found a blog post that showed how to create a custom team for this in Sitecore 5.3.1.
