 * Hi,
 * Those warnings don’t have any relation to the wpDiscuz plugin.
 * Simply, check the paths to make sure:  /home/wp-includes/comment.php

 * Sure, the paths are not pointing to your plugin, but i don’t have anything else
   for comments. Also the error appears when as an admin, i edit some comment within
   your plugin.
 * Anyways, thanks
