There is a problem with the WordPress database format of the rental server. Due to security measures, the database user cannot create it, so it cannot be imported locally. Do you have the MySQL data exported from the rental server imported to your personal computer? Thank you. Server used https://www.xserver.ne.jp/

The specifications of plugins used on WordPress using the easy installation that can be used on the X server and the availability of the MYSQL database cannot be scrutinized by the X server support, so they are not supported.
