Goes to a 500 Page when submitting comment

I'm seeing this, too.

I can confirm that, there is a problem at line 1014 "cannot access object as array" or something like that.
I had to comment out all the following code (lines 1013-1015) in order to get activity back to normal, as one more join is needed to check for comment body in D7:

  if ($antispambot_rules['body'] && !empty($comment->comment_body)) {
  #  $query->condition('c.comment_body', render($comment->comment_body[$comment->language][0]['value']));
  #  $debug_info['Content'] = $comment->mail[$comment->language][0]['value'];
  #  $num_condition++;
  }

Cheers,
Francesco

I'm having a 500 page as well. I've realized this happens when selecting the "Content that has already been identified as spam." option.

This options is in AntiSpam configuration > Anti spam bot options > Identify spam bots by

Above I have selected TypePad as the service.

This happens if all three options in "comment options" are enabled OR not enabled.

"actions against spam bots" options do not seem to make a difference. i get 500 error in google chromium with all three options.

when i turn off "content that has already been identified as spam." comments work.

I believe this is a duplicate of #1483796: AntiSpam fatal error when posting comments..

Please test with the dev version.
