Add Plone site
You can add another Plone site to the server.
The 'Create Classic UI Plone site' button creates a Plone site configured for HTML based output, as was already supported by previous Plone versions. Please consult our developer documentation overview for more information about differences and requirements for these frontends and possible upgrade paths from older Plone versions to Plone 6.
Starting with Plone 6.1, default content is not loaded into the site. If you want to load the default content, you should install the plone.classicui package. If you see this text, that means you have not installed that package yet.
