An example of how to correctly and securely implement TrustedLogin into a distributed WordPress plugin.
To try running out of the box, set the following in wp-config.php:
define( 'TL_DOING_TESTS', true );
This will allow running with the \ReplaceMe namespace.
TrustedLogin is designed not to show anything when there's a failed configuration. This is by design.
Check your site's /wp-uploads/trustedlogin-logs/ directory to see what the logs say (logging is enabled by default).
