I got a bug after change domain name in database. My first domain name was : http://test.website1.io Then I want to change it to yoonaa.com so I use phpmyadmin, access to wp-options table, then change siteurl and home to yoonaa.com.
after a while yoonaa.com works, but yoonaa.com/wp-admin doesn't work. http://test.website1.io/wp-admin still works.
Please help me if you have experienced this.
