hI
please find picture of buttons
https://docs.google.com/document/d/18j7YoV7R6V4rGuseqhoqQ9WPu4fZa9kV/edit
the buttons gpio27 return the correct place holder but in the  place holder for direction buttons 
I think the problem is in this part of the programme

// Replaces placeholder with LED state value
String processor(const String& var) {
  if(var == “STATE”) {
    if(digitalRead(ledPin)) {
      ledState = 1;
      return “forward”;
    }
    else {
      ledState = 0;
      return “backward”;
    }
  }
 return String();

   if(var == “STATE2”) {
    if(digitalRead(ledPin)) {
      ledState = 1;
      return “start”;
    }
    else {
      ledState = 0;
      return “stop”;
    }
  }
    return String();
}

void notifyClients2(String state) {
  ws.textAll(state);
}
void notifyClients(String state2) {
  ws.textAll(state2);
}

hope this makes it clear

Hi.
You have two return String() in your processor() function. Remove the first one.
You also have an issue with your javascript.
You should modify your onMessage() function to something like this:

function onMessage(event) {
  var data = event.data;
  if (data == "ON" || data =="OFF"){
    document.getElementById('state2').innerHTML = event.data;
  }
  if (data == "forward" || data =="backward"){
    document.getElementById('state').innerHTML = event.data;
  }
  console.log(event.data);
}

I hope this helps.
