My issue is that every time someone post new messages/threads it does not show up on the "Last Post" column.  Hit home or refresh button won't do the trick.  You have to restart the application by going to host->host setting before it stays.  If I reboot the server, this seems to fix the issue for a little bit but goes back after a days or so.  Anyone else having this issue?

 You are correct.  This is when the post is submitted and not being moderated.  FYI...I'm running DNN 4.08.04 and forum 4.05.03 on a virtual environment.  It just weird that it takes few hours  for messages to post.  I'll keep investigating.  I'm open for suggestions as well.  Thanks everyone in advance!
