Unable to Authorize LinkedIn App and can't change domain account is associated with

Hi,

Firstly I cannot find a way to change the domain on this account that is associated with the install. The new domain is rugbyfootballconsultants.com.

Secondly I am unable to authorise the LinkedIn App, I saw a ticket had been created by someone else and you had asked for their login details so I have added the information that you need below.

Please can you help us with this issue?

Thanks in advance!
