Hello,

How to access admin cp ? use old domain or new domain ?
Can i change infomation in setting.php file  by manual ?

[.m.]

settings.php file should be changed manually (better to use file editor at the web host control panel)
and after editing settings.php file you should be able to access new domain admin panel to change Site Details

board url => http://ddhocthuat.net
cookie domain => .ddhocthuat.net (note : there is a dot at the beginning)
cookie path => /
