Prevent users from adding pages
This control is now Disable page creation under Settings → POM Tweaks → Content → Pages. Select Enable and Save to prevent new pages for all users on the current site, including administrators.
The normal add-page actions disappear, and WordPress denies direct new-page, REST, and XML-RPC creation requests. Existing pages remain editable and publishable with their normal permissions. Other post types remain unaffected.
Uncheck Enable and save to restore normal creation permissions. Read Prevent new pages while keeping existing pages editable for verification, multisite scope, and limits with importers or custom creation tools.
