Hello :)
My code that I used to do before using WifiManager is as belows.
I used esp8266 as server to turn on/off led.

#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>

char *ssid = "iptime_w";
char *password ="01041538598";
int value=0;
ESP8266WebServer server(80);

void handleOn(){
digitalWrite(LED_BUILTIN,LOW);
value=1;
String message="ONnn!!!";
message += "value : ";
message += value;

server.send(200,"text/plain",message);
}
void handleOff(){
digitalWrite(LED_BUILTIN,HIGH);
value=0;
String message="OFFff"+value;
message += "value : ";
message += value;
server.send(200,"text/plain",message);
}
void handleCurrent(){
String message="";
message += value;
server.send(200,"text/plain",message);
}
void setup(void){
Serial.begin(115200);
WiFi.begin(ssid,password);

while(WiFi.status() != WL_CONNECTED){
delay(500);
Serial.print(".");
}
Serial.println(WiFi.localIP());
server.on("/on",handleOn);
server.on("/off",handleOff);
server.on("/",handleRoot);
server.on("/current",handleCurrent);

server.begin();
pinMode(LED_BUILTIN,OUTPUT);
digitalWrite(LED_BUILTIN,LOW);
value=1;
}
void handleRoot(){
Serial.println("handleRoot");
String message="maidesn!!!"+value;
message += "value : ";
message += value;
server.send(200,"text/plain",message);
}
void loop(){
server.handleClient();
}`

The only problem is that I should hard code ssid and password. so I found wifi manager.
I used basic example of autoconnect.

` #include <ESP8266WiFi.h> //https://github.com/esp8266/Arduino

//needed for library
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h> //https://github.com/tzapu/WiFiManager

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);

//WiFiManager
//Local intialization. Once its business is done, there is no need to keep it around
WiFiManager wifiManager;
//reset saved settings
//wifiManager.resetSettings();

//set custom ip for portal
//wifiManager.setAPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));

//fetches ssid and pass from eeprom and tries to connect
//if it does not connect it starts an access point with the specified name
//here  "AutoConnectAP"
//and goes into a blocking loop awaiting configuration
wifiManager.autoConnect("AutoConnectAP");

//or use this for auto generated name ESP + ChipID
//wifiManager.autoConnect();


//if you get here you have connected to the WiFi
Serial.println("connected...yeey :)");

}

void loop() {
// put your main code here, to run repeatedly:

    server.handleClient();  <---- Can't use it because no access to server object

**but the problem is that I should use server object to display html and control led . like the way I used to call handleOn when address is like http://121.133.222.83:8080/on, ( I already did port forwarding to my private ip 192.168.0.24)
How can I access to server object to use it as I used to do?.(routing like http://ip/current so on. **
