OJS sending many e-mails for a unique notification

Software version: OJS 3.1.2-4
Description of the issue:

Our OJS is sending too much e-mails for a unique notification but it would need to send only one.

We attached a screenshow to help you to identify de root cause of this problem.

Can you help me to fix this?OJS_Error_Screenshot

Hi @Marcio,

I think this has already been fixed in a later release; I’d recommend upgrading.

Hi @asmecher,

Thanks for answer me. I will upgrade it. Is there a guide to upgrade from 3.1.2-4 to 3.2.1-1? If yes, can you send me?

Hi @Marcio,

See docs/UPGRADE.md in the download package.
