After weekend I can’t open via web gui librenms. When I try to open librenms webpage I got http error 500.
I type validate.php and I got that output:
/opt/librenms]$./validate.php
PHP Fatal error: Can’t inherit abstract function LibreNMS\Interfaces\Authentication\Authorizer::authenticate() (previously declared abstract in LibreNMS\Authentication\AuthorizerBase) in /opt/librenms/LibreNMS/Authentication/AuthorizerBase.php on line 33
