Find:

PHP Code:

    foreach ($post_thanks_cash AS $thanks)
    {
        if ($thanks[userid] == $bbuserinfo[userid] AND $thanks[postid] == $post[postid])
        {
            $post_thanks_already ++;
        }
    } 


and replace with this:

PHP Code:

    if ($post_thanks_cash)
    {
        foreach ($post_thanks_cash AS $thanks)
        {
            if ($thanks[userid] == $bbuserinfo[userid] AND $thanks[postid] == $post[postid])
            {
                $post_thanks_already ++;
            }
        }
    } 


Let me know if you get the error in a later place and if you only get the error on pages that dont have any thanks.
