Your validate clearly sais you still in php7.0.

Check you dont have both versions installed. If you are using nginx, remember to restart php-fpm and to change your .sock file to be 7.2 in the nginx vhost conf for librenms

I take snapshoot before installation of php 7.2. So when I rollback I have only php 7.0.
FYI I use Apache for web server.

The cookies are not backwards compatible due to a security fix, clear your browser’s cookies and try again.

thanks for the advice, but it still the same :frowning:

Also, most of the time the issue with the update to PHP 7.2 can be more easily fixed.

Probably your webserver was using an old version of PHP or not pointed to the new PHP fpm socket.
