BuddyPress.org

Hi,

I have a buddy press registration page on my site. Upon registration I can see the user info in wp_users table but no email goes out. For email I have configured WP Mail SMTP Pro and AWS Simple Mail Service (SES). The test email from WP Mail SMTP Pro works fine.

After researching the issue, I found that other people had similar issues and this post helped resolve it https://ast.io/html-emails-buddypress-bbpress/. But in my case it did not help. After applying the suggestions in the post I am getting the following errors. Note that I am using WordPress: 5.4.4 and BuddyPress: 6.2.0.

What am I missing?
Thanks!
