This is the error I also received before manually adding the active private key for abh12345:
I even opened the image into a new tab from steemit.com and it reads the code instantly, but still the same error. I added the key manually again and it was accepted.
Yes, I was looking for a QR code to send steem or something other than a witness add to test, and the qr code worked well for that!
thank you will look into this.
No worries, let me know if you want me to reset and try again.
