Fortiswitch ports not showing - blank page

Hi All,

I have a Fortiswitch 108f connected and authorized on a Fortigate 40f.

Initially I could see all the ports no problem.

After a bit of mucking around I performed a factory reset on the gate. Initially the switch ports stopped displaying occasionally but now they wont display at all. I can see them on the graphic but if I click on the port the screen to the right comes up ("Fortiswitch Ports" but its empty. If I click the "Fortiswitch Ports" from the Menu on the left - same thing - no ports are showing.

Any ideas out there?
