Failure when adding new post or pages

I recently had to back up and restore my multistage. When i restore my site everything works fine however i cannot add new post or pages.
the message I'm receiving is "Are you sure you want to do this? Try again."

I have done the following to fix:
1. Deactivate all plugin
2. Change themes
3. followed the instruction here from
4. and i have attempted the restore in many ways.

I believe it has something to do with my tables but I'm not entirely sure.

I really need help on this one.
