Can you change the RGB to BRG in the settings? I have a ESP8266 with a WS2812 led strip but when I press blue I get green and vice versa. I had wled before and there I could change the color order from RGB to BRG.

I had the same problem. You have to upload the sketch with arduino IDE and change the following lines:
NeoPixelBus\\* strip = NULL;
_ **to** _
NeoPixelBus\\* strip = NULL;
**and**
strip = new NeoPixelBus\(newCount); // and recreate with new count
**to**
strip = new NeoPixelBus\(newCount); // and recreate with new count

This is hardcoded in the Sketch. Maybe we add a binary for future flashing of the flash tool.

Hi.
I am changing the color definitions:
NeoPixelBus\\* strip = NULL;
and:
strip = new NeoPixelBus\(newCount); // and recreate with new count

Please help me.

Looks like you don’t have the neopixel library installed. Add them in arduino library manager.
