Hi Vishnu,
Thanks for your prompt reply. I moved all files as advised by you and then tried to login again into CMC with administrator and my password. It gave me the same message not able to authenticate. I tried again this time just with user name as administrator without password and this time it opened CMC as usual but it gives following error and I am not able to do any thing:-
HTTP status 500- javax.servlet.ServletException:# {setupWizardBean.initializePlugins}
and it also says the server encountered an internal error that prevented it from fulfilling this request.
Kindly advise further.
Thanks
Vijay
