Deprecation: #86323 - Configuration key “site” in YAML site configuration

See Issue #86323


The site configuration is a file called config in a folder called sites and does not need a site key to identify its purpose. To keep writing the config as easy as possible, the site configuration moved one level up and now resides directly in config.yaml .


Having the site configuration below the key “site” has been marked as deprecated and will trigger a PHP E_USER_DEPRECATED error.

Affected Installations

Installations with a site config that have a key “site” are affected.


Remove the “site” key and first level indentation either by directly editing the YAML file or by saving via the sites module.
