Hello everyone,

I tried to update Centreon from version 24.10.12 to 25.10.5 yesterday. The update process worked as expected, but after the update, there were some unexpected issues.

I could not delete hosts and services, could not create new templates, and could not edit existing templates. In some cases, Sometimes when saving it would just throw an empty page. I couldn't find any errors in the log files, and the UI did not throw any exceptions either. 

Cloning services, hosts, and templates works as expected.

I was just wondering if this is a known bug that will be fixed in the next minor update or if this is an edge case.

For testing, I disabled SELinux and removed any security-related, non-Centreon HTTPD configuration.

Thanks in advance!

I would suspect a symfony cache issue after the upgrade.

Hi, thanks for your response, sadly this didn't solve my issue. I reverted back a snapshot to 24.10.12 and patched to the latest minor Version 24.10.17 and then to 25.10.5 and I have the same Problems. I set the logging mode to Debug and enabled all logging Options. Here are errors I found in the logfiles, I don't know if these errors are connected though:

centreon-web.log

The browser does not show anything when trying to delete a host.

Hi, it seems it is calling an api and failed to parse json.

Can you see if you can catch the payload in your browser network tab ? Maybe there is some weird parameter making the internal api fail or something. But that looks like a bug indeed.
