I enter the URL for a site, I get the message that "Error, you already have a key for this site," while the list of existing keys says "You currently have no Site Keys."
When I go to the site key entry point in the site it shows "Looks like you do not have a site key yet."
When I enter the URL in the search box and click, I get a 403.
I was able to generate a site key for another site with no problem.
