Hello!
The problem is:
One user have delete his messages from db. I have manually restore his topics and posts by SQL requests.
Now see the topics in the search but I can't load it because "Bad request. The link you followed is incorrect or outdated."
His restored posts in the topics created by other users displayed well.
I can't understand whats wrong with a restored topics. Or why I have a subj.
How can I debug it?

Solved. The problem was in the field "topics.moved_to" it have to be NULL but it was just empty.
