Hi, I get this error when I click on the link to reset password on my site. I discovered this is coming from GravitySMTP. If I disable it, the email get’s sent, but If I activate it back, I get the error. It’s surprising though that when I send a test email from Gravity SMTP, it get’s sent, but for some reasons, it’s not just connecting with the reset password functionality. I have other sites that I use the GravitySMTP, and the reset emails get sent very well. And the configuration setting are the same.
PHP Fatal error: Uncaught Error: Call to a member function mail() on null in /var/www/html/wp-content/plugins/gravitysmtp/includes/functions_include.php:19
I get this error log from my php-fpm log.
What could the issue be?
