When I want to open a topic :

Database error in vBulletin 3.6.8:

Invalid SQL:
INSERT INTO thread_serviceupdate
(s_threadid, s_updated)
VALUES
('14782', 0);

There is no table "thread_serviceupdate" that comes standard with vb. So, it looks like you installed a hack and then didn't completely uninstall it or you didn't successfully install it in the first place. Try disabling your hacks and see if it works.
