reCaptcha - Again?

Hi,

All of a sudden, sites created with Web Presence Builder, are generating the following error when captcha is enabled on a contact form:

ERROR for site owner:
Invalid domain for site key

Now, I have been able so determine that the client have no way to supply a "site key" for the domain.

The "site key" is configured in /usr/local/sb/config

The problem has been experienced on:

Version = 17.8.12
Build = #2018032616
Revision = 43703
Date = Mon Mar 26 16:58:39 NOVT 2018

Any idea on...

reCaptcha - Again?
