I received the same warning as well.

PHP 7.1 Multisite set up
activation on sub site.

Error occurred on initial set up on test sending page

Message was successfully sent

was the data used for implode an array in the test email?

ie:

if ( isset( $atts[‘attachments’] ) ) {
$attachments = $atts[‘attachments’];
}

Could be a string and not an array…? IDK

or maybe its because its empty? which will then create a lot of logs because typically on a message sent from wordpress there wont be alot of attachments
