Description

Hi there,
I Just added your manager to my project.
https://github.com/The-Coobaz/hunter-hack
I use spiffs to keep web page and css. But When I added the manager, after saving ssid and pass, The spiffs gets cleared. I don't know why id does happen, since I can't find in your library place where the credentials gets saved.

Settings in IDE

Module: NodeMcu, Wemos D1

Additional libraries:

Sketch


#include <Arduino.h>

void setup() {

}

void loop() {

}

The esp saves the credentials on its own wm doesnt save anything. So I suspect you have a esp lib issue or corrupt memory, do a full erase.

Hi. I did as you advised. Did full erase and updated library to current dev version. Everything works now. Thanks for your hint.
