Okay lets start.
We need input.

Give us your /etc/openhab2/services/mqtt.cfg
Give us your /etc/openhab2/items/mqtt.items
Give us a Screenshot of your Sonoff Device>Configuration>MQTT
Do you use openHABian?
openHAB 2.X ? Which one?
Did you read the MQTT Docs ?
Did you read this Topic ? ITEAD Sonoff switches and sockets - cheap ESP8266 Wifi+MQTT hardware
Did you check out the Tasmota Wiki?
