I haven't looked into it much, but it seems you'll have issues with uploading attachments if the posthash doesn't exist.

you might also have issues with quick reply

I'm having this issue, I was using advanced quick reply plugin (which signature stopped working) and disabled it but I doubt that has anything to do with attachments.
Anyway the posthash was blank for 7 attachments and in some cases these 7 attachments will move themselves all to a different post id and thread id....
I fixed the pid and tid in phpMyAdmin but how do I generate posthash for these 7 attachments so this doesn't happen again (the attachments moving posts).

Code:

SET @salt=CONCAT(RAND(),RAND(),RAND(),RAND());
UPDATE mybb_posts SET posthash=MD5(CONCAT(@salt, '-', pid, '-', uid, '-', @salt));
UPDATE mybb_attachments SET posthash=MD5(CONCAT(@salt, '-', pid, '-', uid, '-', @salt));

It shouldn't cause any problems as long as no one is creating/editing a post with attachments at the time you run this.

It works. Thank you Frostschuz!
