I I saw a post that is duplicated, so went on to link that one. When i viewed that post, it is displayed as "Viewed 0 times". I went on replying the post and saw that after the reply, my post also is showing "Viewed 0 times".
One more thing upto yesterday, when we gave kudos, it will display "Kudoed and in the next line Thanks". But now it is "Thanks" only.
Also at this afternoon, i got this message "Forums are closed for maintenance" along with the Lithium Logo.
