I went to the System -> Utilities link, and then clicked on the Current login sessions option to see a list of the current users.
One of the users shown there is the admin user, which for some reason has an outdated email address.
If I click on the admin username, which links to http://x.x.x.x:2199/admin/index.php?page=accounts&action=edit&username=admin, it gives me this error:

Fatal error: Call to a member function find_source_type() on a non-object in /usr/local/centovacast/web/class_AccountEditor.php on line 276

Is there any way to get this resolved?
And is there any other way to edit the admin email address?
Thanks!

Anyone?

Does that email happen to say  : centovacast@centova.com  for the admin ?

I think that is Centova's default email, which doesn't seem to be able to be changed/edited

Nope, it's the email address that Centova was initially set up with.
