I've previously provided instructions for recovering a deleted page (static page) or post (dynamic page) . Retrieval of a deleted page / post involves editing the deleted page / post, using a URL which contains the BlogID, and the PageID / PostID. It's easy enough to get the BlogID - the source listing for any blog page will have multiple places where the BlogID can be found - but where can one find the PageID / PostID? The PageID / PostID can be found - given a small amount of effort, for any well indexed blog. Any cached copy, of the deleted page or post, will provide the PageID / PostID - once you know what to look for.
