I have a bit of a strange bug. I've got my LED strip configured as an Adalight using an Arduino with this sketch.
However, the LED layout refuses to save with any configuration other than the following.
I have ~120 LEDS, so I would like to set 40 on top and bottom and 20 on left and right, but when I click save nothing happens and upon a browser refresh, all settings have reverted. In the logs I see the following message around when I tried to save. What does this mean?
