Hello,
I have configured some alerting rules on a new installation of LibreNMS. Everything seems to work okay except for the fact that I get a weird subject lines in both Email (I’m using the web Gmail client) and Google Chat.
validate.php output:
bash-5.1$ ./validate.php

The subject appears as “{{ $alert->title }} - critical”
The Alert Title in the template is: “{{ $alert->title }}”
It does seem to be specific to alert titles though as “{{ $alert->timestamp }}” and “{{ $alert->uid }}” seem to render fine.
I have enabled “email_html” in the global configuration.
Any ideas on what I could try to make the subject appear correctly?
