I am having the same issue. What I discovered is the key that electrum provided is only 111 characters long. Which means the problem is with electrum not producing the correct length or Woocommerce is looking for the wrong length. Either way I hope this gets fixed soon because it has my whole site stopped dead in its tracks.

The issue may be that I just realized that the Master Public key that Electrum produced is only 111 characters long. According to the error message it is suppose to be 128.
