We'll create fresh WordPress site with Create Stellar Toml installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin creates the /.well-known/stellar.toml file.
You will need ‘manage_options’ capability in order to use the Settings page for this plugin.
NOTE: as with all plugins, once you are no longer using the plugin, you should de-activate it.
This is a good security practice.
