not even able to put a pin on high (esp8266 - espeasy)

Using Arduino Microcontrollers

I have a lolin v3 dev board(ESP-12E) like this one
with espeasy_r120.
I had put a led between D4 and GND
I'm tryin some http command to light up the led, but nothing happens.
The led remain low.
http://192.168.43.245/control?cmd=gpio,4,1
{
"log": "GPIO 4 Set to 1",
"plugin": 1,
"pin": 4,
"mode": "output",
"state": 1
}

http://192.168.43.245/control?cmd=Pulse,4,1,2000
{
"log": "GPIO 4 Pulsed for 2000 mS",
"plugin": 1,
"pin": 4,
"mode": "output",
"state": 1
}

and so on...

The led isn't broken because if I connect it to the 3.3v and GND it works.
Do I have to setup some other parameters? In hardware tab I try to set gpio4 to output high, output low, input, default, but it seems that it doesn't do anything...
please help me

Please say you are using a current-limiting resistor!

The output current capability of the ESP8266 on a per-pin basis must be under 12mA or you run the risk of permanently damaging the chip.
