I logged into Visual Admin and change ume.r3.connection.master.client value and re-started the instance. Now I am unable to login into Visual Admin and getting following error:
Unable to lookup connection Default
http://<hostname>:<port#>/msgserver/text/logon returned empty list of connection parameters
Please help me to revert the changes which I made in Visual Admin. I tried with configtool and restarted the instance but I still not able to login.
