Hello, I manage to create a new server and migrate config and database to it. Now I'm getting no errors on zabbix_server.log neither on syslog. Hots are ok and so.
Instalation on debian 12 mariadb10.11 zabbix7.
The problem is when i access any graph or map, it show nothing.
Any idea what the problem is ?

I manage to find out that the problem was on my zabbix/local/conf/brand.conf.php file
After a new server creation and db upgrades I catch that when apply my rebranding file, it stop working graphs and maps, also the rebranding settings were visible. Maybe some sintax ou identation on the file.
