BuddyPress.org

Hi!
I’m setting up a new website. I’ve chosen Buddypress for registratio, but it’s not sending activation emails. I’ve read many threads but not coming up with a solution.
Here’s what I know:

WP version 4.9.6
Buddypress 3.0.0
WP mail SMTP has been set up by my hosting provider, and it’s working ok. All the test emails arrive correctly.

When I try to register through Buddpress registration form, there’s a sign saying that an email has been sent. But it never arrives there. I’ve checked with gmail, but also but mail@mydomain.com So sure it’s not going to spam folder.

I’ve also tried adding these to my functions.php theme file

add_filter( ‘bp_email_use_wp_mail’, ‘__return_true’ );

That is not working neither.

Is there anything else I can try?
