Upgrade 24.10 to 25.10, mass change display a blank page

My question is did you take any action recently (before migration) related to removal of commands or of service in your centreon ? 

I know centreon can panic if you have services without commands, and the log “The command ID does not exist” makes me think that there is something wrong with your database more than with the software.

Can you try to export the configuration of the poller manually with the Centreon CLI ? 

Command Line API (v1) - CLAPI | Centreon Documentation
It’s the same used for the export of poller configuration, maybe it will point to some issues in your configuration.

Hope it helps.

I do not change anything relevant regarding this, I upgraded last week to the latest version of 24.10 (I do not remember from which version I was coming).

Whats strange is that I can change service by service the command.

What I want to do is to change the “Ping” (Ping-LAN → generic-service) to “Base-Ping-LAN-custom” ( -> Base-Ping-LAN-custom -> Base-Ping-LAN -> generic-active-service-custom -> generic-active-service) to search why I have this behavior

I run the command centreon -u admin -p 'centreon' -a APPLYCFG -v 1, here is the output :

2026-02-20 13:28:21 - APPLYCFG
Configuration files generated for poller '1'

OK: Centreon Poller 1 can restart without problem...

OK: All configuration files copied with success.

OK: A reload signal has been sent to 'XXXXXXXXXXXXXXXX'
Return code end : 0

Thanks for your kind help

ok so there doens’t seem to be an issue within the configuration generation, my asomption was wrong.

Here i have no idea why this weird behavior happends. I would maybe dig into the PHP errors in the servers to try to trace the origin, but i’m clueless here. Sorry

I created a test VM using the available .ova on Virtualbox, I have the same behavior.
 

So the error is not coming from my env but seems general.
