[solved] Error: Either fill all IP settings fields or leave all empty

[dampa]

device: WeMos D1 mini
espeasy: mega-20181025

Got an OLED sheild (64x48 - Driver IC: SSD1306 IIC address: 0x3C or 0x3D) and plugged it into the wemos.
In 'Devices' I added it as a 'Display - OLED SSD1306' - Enabled - I2C Address: 0x3C (60) - (default) Display Size: 68x48

When I hit save a red bar appears under the menu with
Error: Eithor fill all IP settings fields or leave all empty

However the device works properly. When I enter data in the lines and hit submit, the data shows up.

If I 'X' out the message box, next time I hit submit it shows again.

nothing shows on the log.

Take a look at the Config page.
Some elements are missing there.

Dang, you're right! I didn't fill in the 'ESP DSN' (Now how did I miss that) I've filled it in for all my other devices.

Oh well , live and learn.

THANKS!
