A popular hot topic I am hearing from agents is that their domain is still going to their booj site and not moving over to their new kvCORE website. For booj, you most likely set up the DNS to go to booj so in order for your "forward to kvCORE" site to work, we must remove these records from your DNS inside your registar (GoDaddy, etc).
Login to your Registar (we are using godaddy as our example).
Find your domain and go down to DNS settings
Remove the booj DNS Settings, A record & CNAME (for A record, it will be one of the two IP address you see here)
Find those TWO records and remove them! Once you are done, refresh your screen so we can now set up your your forwarding!
Once refreshed, scroll down more on this page until you get to Forwarding. Use the dropdown to select https and then paste your url (no www) - then save.
What about forward with masking? I personally use links from pages on my website for social sharing. If you forward with masking, every page on your website will be the same so it doesn't allow me to grab the actual page links, so for me, that wouldn't work.
