Using pinMode, attachInterrupts() and Wifi Access Point breaks

[WolfBSail]

I have a similar issue as #1020, using ESP12E board. When I am declaring certain pins, using attachInterrupts() and setting up Access Point WiFi in the same void setup() the wifi stops working. I have tested out that if I only declare pins D0, D1, D2, D3, D4, A0 and set up WiFi without the interrupts it does work. Please seen my code below!
I have tried detachInterrupt(), but it did not work.

Does anyone have the same problem? Is there a solution to this problem?

Thank you in advance.

void setup() {
  pinMode(2, INPUT);
  pinMode(1, INPUT);
  pinMode(A0, INPUT_PULLUP);
  pinMode(0, OUTPUT);  //D0

  Serial.begin(9600);

  rtcObject.Begin();
  attachInterrupt(digitalPinToInterrupt(secPin), secondReceive, FALLING);
  attachInterrupt(digitalPinToInterrupt(voltagePin), voltageDrop, FALLING);

  // Init EEPROM
  EEPROM.begin(512);

  // look at whether power-cut time correction is neccessary
  if (EEPROM.read(addr[3]) == 1) {

    clockEnabled = 1;
    startTime = millis();
    Serial.println();
    Serial.println("Blackout has happened, time correction...");
    Serial.println();
    getRtcTime();
    EEPROM.write(addr[6], rtcHour);
    EEPROM.write(addr[7], rtcMinute);
    EEPROM.write(addr[8], rtcSecond);
    powerCutTimeCorrection();
    EEPROM.write(addr[3], 0);
    EEPROM.commit();
    loopTime = millis();
  }
  else {
    configRTC(ntpYear, ntpMonth, ntpDay, ntpHour, ntpMinute, ntpSecond);
    RtcDateTime currentTime = rtcObject.GetDateTime();
    rtcObject.SetDateTime(currentTime);
  }

  //init rtc functions
  rtcObject.SetSquareWavePin(DS3231SquareWavePin_ModeClock);
  rtcObject.SetSquareWavePinClockFrequency(DS3231SquareWaveClock_1Hz); //SQW set to 1Hz

//  detachInterrupt(digitalPinToInterrupt(secPin)); tried these...did not work
//  detachInterrupt(digitalPinToInterrupt(voltagePin));

  //creating the ESP's own network
  WiFi.disconnect();
  WiFi.mode(WIFI_AP);
  WiFi.softAPConfig(apIP, apIP, IPAddress(255, 255, 255, 0));
  WiFi.softAP(ssidESP, passwordESP);
  Serial.print("Connected to ");
  Serial.println(ssidESP);
  Serial.print("Access Point IP address = ");
  Serial.println(WiFi.softAPIP());
  Serial.println("");


  handleWebsite();   // crating html string;
  dnsServer.start(DNS_PORT, "*", apIP);
  server.on("/", handleWebsite);
  server.on("/generate_204", handleWebsite); // for android captive
  server.on("/fwlink", handleWebsite);       // windows captive
  server.begin();

  server.onNotFound([]() {
    server.send(200, "text/html", webSite);
  });

  webSocket.begin();
  webSocket.onEvent(webSocketEvent);

}
