How can I fix this l have tried binding to other buttons plz help

How did you make L1 quit? It is not by default?

Anyway, you can use the Defaults button on the keyboard page to reset all key/joystick binds to default, click apply, then redo your settings.

If you do not want to lose all your settings, then you would have to tell me what device and controller you are using, then I can help from there.

I was on a HP stream 11 windows 10 and with a ipega controller and yes resetting to default is the same

When you try to bind the button to a different command, what does it say the button is called in the Keyboard Input menu?

I cant do it in the input menu pressing it goes back to options page I tried /bind .
I am going to get another controller soon and see if its the same.

It's possible that the controller's internal mapping is not conforming to the standard Windows gamepad mapping.

Which exact ipega model do you have?

Fixed the problem was in config file I changed the joybutton6 from "quit" to +Shoot2
