view -> error, copy to facebook shows wrong post….

Using WP 3, Suffusion 3.6.6.
I have been building pages and have moved some posts to pages (Deleted posts, created pages.) 17 pages, 4 posts, 3 comments.
I am experiencing the following problems

1) clicking on “view post” from editing window get error:
Error 404 – Not Found
Sorry, the page that you are looking for does not exist.
Going directly to front post address, all pages (currently tapeworm format) show correctly.
2) Pasting the url, https://me.com for the front page and blogs to Facebook shows not the current blog but an earlier version of the previous piece (in the middle).

Data base issue? How to approach? Muchas gracias!
