wp_mail failed: Undefined index

Hi Pascal,

I see you’re using bbp-private-groups plugin. Please try deactivating it as a test. Note that my plugin just spits out the latest error at that point in the code. Unfortunately, it’s not always something related to the messaging. The undefined index error that you are seeing is being thrown by bbp-private-groups.

If you’re using wpMandrill, then the messages might be hitting a blacklist.

You can add some debugging to line 443 to see each email address to be processed in the loop:

442:    $email = ( $recipient_id == -1 ) ? get_bloginfo( 'admin_email' ) : ( string ) $user_info->user_email ;
443: error_log(__LINE__ . ' Email is: ' . print_r($email,1), 3, dirname( __FILE__ ) . '/out.log'); // Added debugging
444:	if ( false === apply_filters( 'bbpnns_dry_run', false ) )

Let me know what you find.

Cheers,
Vinny

Hi Vinny,
Just wanted to ask how you saw I was using bbp-private-groups… now I see it’s referring to that plugin in the error ??
OK, will try later today to deactivate it and see. Will get back to you later, thanks for your quick reply !

Hi,
Resetting the name of Group 2 in bbp-private-groups seems to have worked to at least solve this issue.
