Thank you very much for your reply.
There are no other errors. and
All formatted and reinstalled, but it does not work.
My WordPress site address is “www.?????.?? (Korean language domain.)”
Among hosting companies: “www.cafe24.com”
The server environment is: UTF-8 (PHP7.0, mariadb-10.0.x).
Is the server environment a problem?
Thank you for your help.
