when i want to hide then delete an answer , QA shows me this error page :
Question2Answer query failed:
DELETE FROM qa_posts WHERE postid=264
Error 1451: Cannot delete or update a parent row: a foreign key constraint fails (`admin_qa`.`qa_posts`, CONSTRAINT `qa_posts_ibfk_2` FOREIGN KEY (`parentid`) REFERENCES `qa_posts` (`postid`))
It's about the related question to an answer!
when a question has an answer and the answer has a related question , if you click on the delete parent , it shows you this error.
Its better to show a message on same page!
