Pull Request for Issue #46404 .
sysinfo was incorrectly checking for the compat plugin it should have been checking for the compat6 plugin
Go to the system information and check the value/setting for the backwards compatibility plugin
Reports as disabled because it is looking for the j5 plugin
Correctly reports the status of the j6 plugin and its settings

Thank you @brianteeman for your work on this and a thankyou to all the testers
Hello, some thing strange, i on j5.4 and looking to update to j6, on the update tool i see :
The 'Behaviour - Backward Compatibility' plugin is disabled
Go to ['System - Manage - Plugins'] and disable the plugin.
Checked : No
The 'Behaviour - Backward Compatibility 6' plugin is enabled
Checked : Yes
In the extensions manager i see both enabled.
In the sql table i see both enabled.
btw, i updated the two lines (compat6 instead of compat) in the SysinfoModel.php
@hmed95 The result of the check for the 1st plugin says "No", so it is NOT disabled. But you have to disable it before updating to 6.
This has been discussed here several times. An improvement will be available with 5.4.1, which will be released on next Tuesday, which makes these checks more understandable (or less confusing). See #46324 .
Thanks, i updated the the latest rc (Joomla! 5.4.1-rc2 Release Candidate [ Kutegemea ] 18-November-2025 18:00 GMT) but to update to j6, when i disable this plugin it show me an error (An error has occurred. 0 Class "JFactory" not found), i enabled it again on the mysql table.
I missed some thing ?

@hmed95 When you disable the plugin and that error is shown, it means that you have a 3rd party extension which is not compatible with Joomla 5 and so needs the Joomla 5 b/c plugin. This wouzld not work anymore on Joomla 6, and it could make the update break in the middle. That's why Joomla forces you to switch it off before the update. If you then have an error, you can investigate it (switch on debug and set error_reporting to maximum in configuration.php so you see the stack trace and can identify the problematic extension. Then you can enable the plugin again in database and fix that e.g. by updating that extension to newer version.
All that is described here: https://manual.joomla.org/migrations/54-60/compat-plugin/
ANd it has nothing to do with this PR here where you are commenting because this PR here handles the Joomla 6 plugin in Joomla 6.
Thanks, its seems thats related to joomla, not ?
My bad, thanks a lot problem resolved, it was coming from stackideas plugin, i didnt reconize it with the Foundry name.
Fixed.
