-for the “#” issue, I’ve updated file page.php with post #2768 commented and restarted the server. It does work for the first post or page a user reads. But the sign ‘#’ at the end of url still appears, for example, after you click to open any post/page, CROSS to close it, click to open any other page/post again, and then also CROSS to close it.
-for the fbseocomments plugin issue, I’ll follow your suggestion later.
Thanks for your great help! ^O^
