Bug: Upgrading from 1.5.2 produces error on settings page

[M-Davies]

I have recently upgraded my Faction install from 1.5.2 to 1.6.9 (latest at the time of writing). However, I'm now consistently getting an error on the admin settings page (/portal/Options):

This seems to occur no matter the settings I change. I suspect it's due to an outdated config or something that hasn't been cleared up. Details on my setup can be found in issue #82

Thanks :)

Similarly, editing custom variables seems to be broken due to this:

When I press the edit button, this toast is shown and the app never gives me a chance to change anything

I think this is a browser cache issue. Try clearing cache and try again

Ah grant thanks @summitt , that did the trick
