Possibly you need to update to PHP 5.6You may also need to apply this PR:Fix service & reponse times on dashboardhttps://github.com/osTicket/osTicket/pull/3738git pull origin refs/pull/3738/headI thought there was another PR also, however from just a quick look I think I now only apply that one.I have a branch on my fork also which adds a little further logging into the dashboard stats. It logs when assignments happen automatically either by auto-assignment or when closing someone else's ticket.When this is applied the graphs tend to show equal amounts of "created", "assigned", and then "closed" values.
