Unable to traverse VLANs

Huge networking noob here. I've mainly been a SysAdmin most of my career but have recently had to run double duty so would appreciate any help/guidance you can provide for a novice.

I have an Aruba 5406R as my aggregation switch, which was recently replaced. Since then I'm unable to traverse VLANs or reach my default gateway (Fortigate firewall @ 10.3.0.10) from any VLAN other than VLAN 1.

This was recently refreshed Procurve 5406 ZL to Aruba 5406 ZL2. The only thing thing that changed in the hardware replacement was the config. The IP of the switch & router ID changed from 10.3.0.3 to 10.3.1.1 to clean up some sloppy IP management. Here's a snippet of my config. I'm at a complete loss as to why VLAN4 can't reach VLAN 1.
