 If you use djangocms-versioning or djangocms-moderation, you can have snippets versioned and moderated by
 adding the following to your settings::
 
-    DJANGOCMS_SNIPPET_VERSIONING = True  # Set to version with djangocms-versioning
-    DJANGOCMS_SNIPPET_MODERATION = True  # Set to moderate with djangocms-moderation
+    DJANGOCMS_SNIPPET_VERSIONING_ENABLED = True  # Set to version with djangocms-versioning
+    DJANGOCMS_SNIPPET_MODERATION_ENABLED = True  # Set to moderate with djangocms-moderation
 
 If you enable versioning (e.g., set `DJANGOCMS_SNIPPET_VERSIONING = True`) for djangocms-snippets in a project that already contains snippets, you will need to create `Version` objects for those existing snippets using the `create_version` management command provided by djangocms-versioning.
