I found out that the user that I am trying to delete send a pm to other user, and the other user has not delete that user's pm, causing the conflict when I am trying to delete. Is there a way to resolve this? I tried with 1.9.8, the issue is still there.

It's a bug... Fixed in newer versions of YAF. "When you are grateful, fear disappears and abundance appears”."

Jaben, if I implement ON DELETE CASCADE, would that be a good idea or bad ?
Also, what happens if I remove the FK out?

That would be a good idea -- as it would fix your problem right now. "When you are grateful, fear disappears and abundance appears”."

Jaben, one more question if I want to put that, where is the SQL statement that I can put that on delete cascade?

Jaben, if I implement that, the PM message gets deleted too, no? Even though the other user has not read the message yet.

Yes. This is why it's not a simplistic fix and was only really fixed in newer versions. "When you are grateful, fear disappears and abundance appears”."
