Version v1.8.1.2There appears to be a bug in class.thread.php on line 894 : if ($thread = ThreadEntry:($match))lookupByMessageId requires 2 arguments, where only 1 is supplied by the above call. (function lookupByMessageId($mid, $from) {)$from is missing from the call to the function, however I'm not sure what $from is. I'm assuming it's an email address.. any ideas?Thanks,
