Thanks Shahriar!
I have changed nothing in the email templates, i.e., the password-reset template looks like this:
You have requested for your password to be reset.<br/>Please confirm by clicking the button below: [#reset_password#]<br/>No action required if you did not request it.</b><br/><br/>Best Regards,<br/>Support Team<br/><b>[#sitename#]</b>
But the email I am getting is totaly diffrent:
Hi infonviz,
This notice confirms that your password was changed on nVIZ GmbH.
If you did not change your password, please contact the Site Administrator at ir@nviz.de
This email has been sent to info@nviz.de
Regards,
All at nVIZ GmbH
What have I broken?
