Ran into this problem:

TRUNCATE  `qa_words`

MySQL said: Documentation

#1701 - Cannot truncate a table referenced in a foreign key constraint (`mydatabase`.`qa_posttags`, CONSTRAINT `qa_posttags_ibfk_2` FOREIGN KEY (`wordid`) REFERENCES `mydatabase`.`qa_words` (`wordid`))
Q2A version: 1.7.4

Sounds cheap, but I just used:

DELETE FROM `qa_words`
by
qa_words being  one of the core table which links tags, category names, hence mysql throws an error for foreign key constraints. you can set foreign key constraints to zero and then run truncate. That should do.
