Last week, .myDomainregistry upgraded their registration and modification system to enhance the overall performance. Certain addresses and URLs have been changed to reflect the new system. If you need to modify your domain name (.my extensions only) kindly follow this link
The new system also require you to log in using handle. If you could not remember your handle, you can conduct whois to check the correct Admin/billing or technical handle. You can conduct whois here or at the registry’s web site.
