nodeMCU not saving changes from web GUI.

I've tried several times to change the settings and it seems to be finicky on what it saves. I'm using a setup of 10 MCUs and some have no issues while others won't save. Any thoughts?

Hi potentstudios ,

You can try to erase the esp8266.

This fix the problem for me.

Thanks I'll try that!

I have experienced the same issue but haven't found the culprit yet

Maybe this part of the setup routine?

// Check if SPIFFS formatted
  if (SPIFFS.exists("/formatted.txt")) {
    SPIFFS.format();

    File f = SPIFFS.open("/formatted.txt", "w");
    f.print("Formatted");
    f.close();
  }

It should be more like this right?

// Check if SPIFFS formatted
  if (!SPIFFS.exists("/formatted.txt")) {
    SPIFFS.format();

    File f = SPIFFS.open("/formatted.txt", "w");
    f.print("Formatted");
    f.close();
  }

The solution proposed by bombcheck worked for me with beta5g. Currently SPIFFS is wiped every time the system restarts.

Has anyone else tested/confirmed bombcheck's fix?
