Hi,
I've installed jira 6 and imported data from jira 5.
Everything work perfectly but not the dashboard.
The dashboard isn't displaying correctly the widgets. Most of the time, they stay empty and activity stream display "An error occurred while trying to retrieve recent activity.".

Sometimes, some of them are displayed:


I have checked the logs and I doesn't see any errors when refreshing the page.
I have tried to disable every plugin, disable some widgets but it doesn't change anything.
It is a WAR installation on linux with ssl + proxy. Proxy +ssl are configured in sever.xml.
I have searched for hours, but i haven't seen similar problems
Thanks for your help!
