    I have WP Mail SMTP (version 1.6.2) installed on a multisite and i get this error on the Email test page:

    Fatal error: Uncaught Error: Call to a member function is_mailer_complete() on null in [path]/wp-content/plugins/wp-mail-smtp/src/Admin/Pages/TestTab.php:101

    WP 5.2.3
    PHP 7.3.9-1

  • Hi @corsac,

    This could be due to the conflict with any other plugins. Please follow the troubleshooting guide to find the conflict if any. This could also be temporary during the WordPress update, go to Dashboard -> Updates -> Check again -> Update.

    I hope this helps!

    Thanks for responding @sanzeeb3,

    It turns out it was a typo in my wp-config.php
    I had define( 'WPMS_MAILER', 'smpt' );
    Instead of define( 'WPMS_MAILER', 'smtp' );

    Glad to know you sorted it out and thanks for letting us know.

    Have a good one 🙂
