I had the Dark theme enabled prior to upgrading (wasn't actually intending on upgrading but my USB stick died). I managed to get my old usb drive to mount on another machine once out of the 30+ times attempted to mount and made an image. After restoring the image to a new drive I can get the system to boot and load all of my previous settings but it went through an upgrade from 6.5.3 to 6.6.1 and now I cant access anything. Yes I know that it says "Invalid Key" I was logging in to fix it.
Is there somewhere that I can access the webui settings to revert it to a usable state? System is up, on the network, accessible via SSH and through http but is unusable in the sense that I cant start the array with an invalid key.
