Problem solved. I forgot to edit a plugin again after reinstalling the product

u will need to edit the plugin named "Thread Auto Reply - Part 2" as follows:
search for:

$msgs = @explode("\n", $vbulletin->options['coder_autoreply_text']);
$msg = $msgs[@array_rand($msgs)];

replace it with:

$msg = $vbulletin->options['coder_autoreply_text'];
