Steve, we have received this kind of report several times from other users, but were not able to reproduce it.

1. How many user roles do you have on your site?
2. How often your cron runs?
3. Can you check your mail server's email logs?
4. Does this happen to all users? or to the users with certain mail client ( gmail, hotmail. yahoo and etc.)?

I only have 3 roles set up.  Of those I only use 2 on my mass emailing.  The cron was set to once per minute.   It is sending out multiple emails.  It used to work fine and I have not messed with the email stuff at all.

Regards,

Steve

I have emailed you some logs provided by the hosting service.

Update: Steve migrated to new host and issue with mass mailing disappeared.

Hi all! my site is sending hundreds of emails per day and users are complaining, even users who deleted their accounts. The problem does not affect all users. I have 5 user roles in my site and cron runs every minute. I think the problem started when update the plugin Reminder Notifications. I deactivate the plugin and the problem persist. I contacted to the plugin developer and he told me there is a problem with my site cron. Any idea where to start to try find out the problem?

the problem is i cant click the free user when change user to other role

maybe this will make oxwall sending multiple copies email

one user two role which is free and vip

Pablo,

Have you noticed anything in common in those users who do receive multiple emails?
Check ow_base_mail table of your database. Does it contain any data related to your mass mailing?

>>the problem is i cant click the free user when change user to other role

Not sure that I understood the point.

okay, lets say i want to make A as VIP user than i click VIP for A, but I could not make A not as a free member then i submit.

A will have two role which is as free member and VIP member. so email sending twice

Thanks Aliia. I deleted all rows from ow_base_mail table, Now just wating for news from users.

Ben,

Even if user is assigned to more then one role, he will get only one email. I have tested this a couple of times, just to make sure.

If on your site you are receiving emails twice because you are subscribed to two user roles, I will be glad to check this for you if you can provide needed access details.

im not creating any role on my site yet, just testing steve issue on my local pc and can't click the free role. Thank you alia,

Well, yes, you will not be able to click on it.

Here is a little "hack" for those who want to make default user role clickable: http://www.oxwall.org/forum/topic/7897?page=2#post-39324

I wrote this down a while ago and have not tested in 1.5.3. So if somebody finds out that this  no longer works with the latest version of Oxwall, let me know.

Suddenly I am having the doubles issue at Mass mailing and invite system,,, and I haven't made any changes, not to crons nor user roles.

Do you use default invite system in the admin panel or contact importer?

Can you please share your URL? I will register and you'll send a test mass mail? as we cannot reproduce the issue. 

I have been testing it using mass mailing from admin panel at: admin/mass-mailing I include my User role as Owner, doubles up each time.

I will need Cpanel access details and admin details for the website, please PM

Krunch I could not reproduce the issue on your website, see screenshots in your PM
