I have taken over the management of a site running on concrete5 but I am unable to add any new features because I get an error saying I need to re-connect with concrete5.org. I can't find anywhere in the interface where the registered account is listed or any connection information is contained. I don't know the account, and all the email addresses I have tried do not respond with password change opportunities. How do I determine what account the site is linked to, and how do I correct it as the previous folks have moved on?

I have tried searching through the forums and didn't find anything helpful on this subject. I can't believe I am the first with this problem.
