csv imort into mysql DB, problem with previous, next post

[ Moderator note: moved to Fixing WordPress. ]

Hi all! After my import csv file to mysql, I see all posts well, but previous and next post on the bottom page crashed. I see only 2 test post I made from admin panel and 1-st post from csv file…(( So, prev and next buttons transfer between 3 post (I have more!) I check wp_postmeta, wp_posts, wp_term_relationships, but I think all good whith data…
Anybody know why after my import I see this problem whit neighbord posts? Thanks for help!
