 * Hi [@corsac](https://wordpress.org/support/users/corsac/),
 * This could be due to the conflict with any other plugins. Please follow the [troubleshooting guide](https://www.wpbeginner.com/beginners-guide/beginners-guide-to-troubleshooting-wordpress-errors-step-by-step/)
   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](https://wordpress.org/support/users/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' );`
