Pluing FeatureFlags update matomo5

Hi,
After updating matomo on my server, I get an error message. I can’t find the pluing to add in the downloads on the matomo site
"A fatal error occurred
The following error just broke Matomo (v5.2.0):
Class ‘Piwik\Plugins\FeatureFlags\FeatureFlagManager’ not found
in /home/hbrulle/matomo.lp-henribrulle.fr/plugins/CoreHome/Controller.php line 58"

Thanks for your help

Hi @couponne33
It seems it is a new Core plugin from Matomo 5.x
Its path is: piwik\plugins\FeatureFlags and I can see FeatureFlagManager.php ifle in it.
Maybe this is missing from your installation?
Maybe you must activete this plugin in the Matomo plugin manager?

hi Philippe,
I’ve found a way to add the missing folder to the pluing, but I get another error message. I don’t know what to do

An error occurred

No entry or class found for ‘dev.disable_plugin_update_checks’

Thanks

Hi @couponne33
I suggest you download again the whole Matomo application and activated plugins. Probably some files are missing?
