BuddyPress.org

Hello. My website puzzleprime.com does not send out activation emails. I am using WP Mail SMTP. I found THIS SOLUTION but I don’t think the BP code on my website needs fixing:

		'core-user-registration' => array(
			/* translators: do not remove {} brackets or translate its contents. */
			'post_title'   => __( '[{{{site.name}}}] Activate your account', 'buddypress' ),
			/* translators: do not remove {} brackets or translate its contents. */
			'post_content' => __( "Thanks for registering!\n\nTo complete the activation of your account, go to the following link and click on the <strong>Activate</strong> button:\n<a href=\"{{{activate.url}}}\">{{{activate.url}}}</a>\n\nIf the 'Activation Key' field is empty, copy and paste the following into the field - {{key}}", 'buddypress' ),
			/* translators: do not remove {} brackets or translate its contents. */
			'post_excerpt' => __( "Thanks for registering!\n\nTo complete the activation of your account, go to the following link and click on the 'Activate' button: {{{activate.url}}}\n\nIf the 'Activation Key' field is empty, copy and paste the following into the field - {{key}}", 'buddypress' )
		),
		'core-user-registration-with-blog' => array(
			/* translators: do not remove {} brackets or translate its contents. */
			'post_title'   => __( '[{{{site.name}}}] Activate {{{user-site.url}}}', 'buddypress' ),
			/* translators: do not remove {} brackets or translate its contents. */
			'post_content' => __( "Thanks for registering!\n\nTo complete the activation of your account and site, go to the following link: <a href=\"{{{activate-site.url}}}\">{{{activate-site.url}}}</a>.\n\nAfter you activate, you can visit your site at <a href=\"{{{user-site.url}}}\">{{{user-site.url}}}</a>.", 'buddypress' ),
			/* translators: do not remove {} brackets or translate its contents. */
			'post_excerpt' => __( "Thanks for registering!\n\nTo complete the activation of your account and site, go to the following link: {{{activate-site.url}}}\n\nAfter you activate, you can visit your site at {{{user-site.url}}}.", 'buddypress' ),
			// 'args'         => array(
			// 	'multisite' => true,
			// ),
		),

Any idea how to fix the issue? Test emails work fine so that issue must be with BuddyPress.
