Hi team,
I am using ESP8266 in that i am working with wifi manager i have downloaded the wifi library and i am using the example code of wifi manager

#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.setAPStaticIPConfig(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:
    
}

In this code run successfully without any error but when i connect to try to connect the SSID it is not discovering as AutoConnectAP i dont why i have followed these link

You do not see the access point?

Hi,
I have problem compiling WiFiManager for Wemos D1, even when I try to compile example for WiFiManager.

This is error message what I get:

Why are you not posting your own issue for this?

Use the beta

@belazelkos For this error basically it boiled down to me having two versions of wifimanager installed. And the only way I found that out, was it reported I had .15 beta installed, so I uninstalled that through the library manager, then it reported that .14 was magically installed so I uninstalled that. I then from that point, installed .15 beta and it compiled and worked for me. I was getting the exact error as you. Hope this helps someone because I wasted a good 4 hours debugging this.
