have you clicked on the top left corner to change feature value.  It is a toggle switch like 1.72 i believe.    Is this just on the DBoard page?

index page, groups , video are showing online users, but not the dashboard

dashboard not working javascript 

have  you tried running the console to see what it shows?

only this 

Message: Can't generate URI! Route `fbconnect_configuration_fields` not found!
\public_html/ow_core/router.php
Line: 262

i assume you have a FB connect plugin, try disabling that and see if that solves the issue. There seems to be a conflict someplace. 

I have deactivated the newsfeed plugin and all works OK in dashboard

but after activating newsfeed, java dont work

fb plugin needs for update, 

found it

attachment plugin needs for an update  :D

great detective work... excellent!  (i was just reading a post on that very issue)
