ok done...found the error under defaulte templates ->index templates -> index
had 2 x sidebar floats - <div style="float:{$right};width:19%;">{$sidebar}</div></div> and removed the one
I found a problem
If i make a new topic or reply on something the side bar will give all the recent posts the same time.
As you can see if i will make a new topic or reply now all recent posts time will go to 1 minute ago its following the new reply time
can i put it into portal page ?
That kind of sidebar is a default option in portal page. You can enable it in ACP portal settings.
