Following a long illness I find I cant access my membership site forum. It is linked to my wordpress site via an SSO link which was installed back in 2017 by a developer who I am no longer in touch with. I don't have the details of the link. Can you advise what can be done? I need to access my forum as it is the main teaching hub of my site. I manage to get onto my wordpress site OK but when asked to put in my login details to the forum , it is refused.
