Hello,
I installed this plugin and it was not working. So I decreased the limit in the mail plugin PHP file – mass-mailer.php:
SELECT email_user_id, email_optout FROM {$wpdb->base_prefix}mass_mailer WHERE email_optout<>'no' AND email_status = 'no' LIMIT 500
Changed to:
SELECT email_user_id, email_optout FROM {$wpdb->base_prefix}mass_mailer WHERE email_optout<>'no' AND email_status = 'no' LIMIT 20
Now the plugin works. We used Google Mail SMTP on that site, so the limit might be different for other hosts.
Suggestion for plugin author: I guess this should be in plugin options and the default should be much lower than 500.
Thanks,
Martin
