Hi

I recently changed my domain name and I have just tried to extend and re-connect to community. But I get error message

The base URL of your site does not match a registered instance of the site. Please click below to authenticate your site again.

Project Page
Your project page URL is:
http://www.concrete5.org/private/sites/jzteupshsrbvgra0yobv9k4h...

But when I attempt to login with my user-name and password:
I get message:
You must login with a username that is an owner or editor of this project.

I had this written down and I either made an error, but there is no way I can see to reset or get a password reset .

Any idea how I can re-connect my new domain URL to the community ?

Thanks all !
