I made Wordpress multi-site, and I can no longer access the management screen on the following page.
The management screen of the site http://example.com/ that originally existed when it became a multi-site cannot be accessed, and the following url appears and redirects. This is a newly created site
You can log in to the management screen of http://example.com/sub.
The login ID is the same for both the subsite and the original site.
What you want to achieve
Log in from http://example.com/admin.
Problems / error messages that are occurring.
The management screen of the following url is displayed
https://example.com?redirect_to=https%3A%2F%2Flemon-site.work%2Fwp%2Fwp-admin%2F&reauth=1
What I tried.
Add the following to wp-config.php.
define( 'WP_SITEURL', 'http://example.com' );
define( 'WP_HOME', 'http://example.com' );
