Changing all Passwords mail will not be sent

Hi Community,

I just started using Login Security Plugin and am convinced of its high potential and would love to use it for my website. I set it up and it seems to work perfectly fine. I was urged to change the password for all other users apart from the administrator after the install. I went ahead and did that. This resulted not only in all users having to change their password but also me as administrator having to change my password for some reason I am not aware of. When entering my usual username and password I am informed that my PW has to be updated, I am prompted to enter my email address and a mail with the updatelink will be sent to me. I enter the email address but the mail does not get sent. I get the message “mail could not be sent. Possible reasons the function mail() is deactivated”. Same happens to all other users.

I did not find this function setting or the reason for the mails not being sent.

Please let me know if you are aware of this issue and have a possible solution. I would really appreciate it.

Best regards,
Max
