[PS 1.7.6] Module mail alert deactivated but send outofstock mails

[cryoth]

Hi there !

I'm facing another issue but with the ps_mail_alert module this time.

The module is deactivated in all my stores but the last 2 weeks my website is sending outofstock mails to all my staff members and even to some customers.

I know those mail are usually triggered when there is a stock update but is there any other way those mail can be send except ps_mail_alert ?

For the information i'm not using an other stock alert module.

Here is my ps_mail_alert config : 

 

Any help would be really appreciated =)
