Is mosaic required for Plone 5.1

I just installed Plone 5.1b4.

I can edit the 'Welcome' page, but adding new pages does not 'have any content' (the html of 'content' is empty, also without a theme enabled'.

If I install plone.app.mosaic, it works (even if the content type does not use mosaic layout.

Is Mosaic required for Plone 5.1 ?

Mosaic is not required, if not you would not have to install it :slight_smile:

It's a bundled add-on, just like restapi is also there available, or plone.app.iterate.

The idea is to make it bring it to the core and maybe even make it the default, but that's going to be roadmapware unless someone works on it and PLIPs it.

this is actually a bug in 5.1b4, try 5.1b3 or wait for 5.1b5.

see: https://github.com/plone/Products.CMFPlone/pull/2106

Or you can add this to your packages somewhere in a configure.zcml:

<configure zcml:condition="installed Products.CMFDefault">
        <exclude package="Products.CMFDefault.browser" file="configure.zcml" />
        <exclude package="Products.CMFDefault.formlib" file="configure.zcml" />
        <exclude package="Products.CMFDefault.upgrade" file="configure.zcml" />
</configure>

Thanks, ... I thought it was my setup
