How do I fix this problem and how do I login again?
The Matomo Super User can manually edit the file /path/to/matomo/config/config.ini.php
and add the following lines:
[General] trusted_hosts[] = "enspectacle.ca"After making the change, you will be able to login again.
You may also disable this security feature (not recommended). To do so edit config/config.ini.php and add:
[General] enable_trusted_host_check=0
