reports empty since 5.4/5.4.1 update (using WAN2)

[CyberNorris]

We have a client with a FGT 100D that was updated from 5.2.7 to 5.4.1 to support FortiSwitch management. It uses WAN2 for it's current outside link. Since the upgrade, all report data except admin logins and changes is empty. We used to get good data on bandwidth, AV, attacks, botnet, etc. It's like the updated reporting now ignores WAN2.

Any ideas on how to make this work again?
