Trouble Sending Test Email

Hello,

I’m trying to setup the plugin for a multisite, and I followed the documentation for setting up with Sendgrid. When I got to the step to send a test email it won’t let me and says my Mailer is not properly configured. Not sure what’s wrong? Here is what I put in my wp-config.php. The settings seem to have taken, as when I go to my sites all the options are set.

define( ‘WPMS_ON’, true );

define( ‘WPMS_MAIL_FROM’, ’[email protected]’ );
define( ‘WPMS_MAIL_FROM_FORCE’, true );
define( ‘WPMS_MAIL_FROM_NAME’, ‘From Name – No Reply’ );
define( ‘WPMS_MAIL_FROM_NAME_FORCE’, true );
define( ‘WPMS_MAILER’, ‘sendgrid’ );
define( ‘WPMS_SET_RETURN_PATH’, true );

define( ‘WPMS_SMTP_HOST’, ‘smtp.sendgrid.net’ );
define( ‘WPMS_SMTP_PORT’, 465 );
define( ‘WPMS_SSL’, ‘ssl’ );
define( ‘WPMS_SMTP_AUTH’, true );
define( ‘WPMS_SMTP_USER’, ‘apikey’ );
define( ‘WPMS_SMTP_PASS’, ‘mysendgridapikeyhere’ );
define( ‘WPMS_SMTP_AUTOTLS’, true );

define( ‘WPMS_GMAIL_CLIENT_ID’, ” );
define( ‘WPMS_GMAIL_CLIENT_SECRET’, ” );

define( ‘WPMS_MAILGUN_API_KEY’, ” );
define( ‘WPMS_MAILGUN_DOMAIN’, ” );
define( ‘WPMS_MAILGUN_REGION’, ‘US’ );

define( ‘WPMS_SENDGRID_API_KEY’, ‘mysendgridapikeyhere’ );
