Query: SELECT * FROM mybb_attachments WHERE pid IN ()</message>
</error>

while accessing "abandoned" threads in archive mode. With "abandoned" I mean threads which exists in mybb_threads table but do not have any posts in mybb_posts - probably because of MyBB or DB error (e.g. restarting DB server, timeout, race condition etc.).

Simple patch: [attachment=14188]

Nicely found...! Patch seems to fix the problem...

Personally I'd favor not running the query at all in there is nothing to look up, but the fix does work fine.

So, really, a fix could be:

$pids = implode(",", $pids);

if($pids)
{
	// Build attachments cache
	$query = $db->simple_select("attachments", "*", "pid IN ({$pids})");
	while($attachment = $db->fetch_array($query))
	{
		$acache[$attachment['pid']][$attachment['aid']] = $attachment;
	}
}

Yes, that sounds better
