This is not on our supported domain, but listed domain www.ytgrow.us (Can't change supported domain, it won't let me).
"PLEASE READ FIRST"

We are currently in the process of moving sites around and building everything around this domain (we are having a purpose built multi database login system being created for the website), so our user base and main database belongs to this website. This also includes the core function of Jomsocial (it's being used on all our domains, but this is the main).

Most of the database for www.ytgrow.us will be copied for www.worldseriesgaming.co.uk , including the functionality of Jomsocial IE: Jomsocial is shared between both sites. But this came up today (wasn't there yesterday) and has now stopped us from working further as we don't have access to the jomsocial admin console (no core edits have been done as of yet). We need help on this, as it is part of the main domain.

We have tried to reinstall and not remove, as we have a user base.

Hi, Matthew.
