According to your advice, I received the following message:
sudo ./bnconfig --email@example.com whitesilver.club/wordpress
Error: There has been an error.
Use --help to get a list of valid options
Apart from the above, I cannot display even my login screen at present.
The login screen was displayed at first, but now I cannot access the WordPress with "user" so any error message was received.
I would like you to confirm my script of 'apps/wordpress/htdocs/wp-config.php' file:
/* That's all, stop editing! Happy blogging. */
* The WP_SITEURL and WP_HOME options are configured to access from any hostname or IP address.
* If you want to access only from an specific domain, you can modify them. For example:
I look forward to hearing from you.
