I am trying to add a blog to a SilverStripe site using the Blog Module.

The package seemed to install fine via

composer require silverstripe/blog

and dev/build returned no errors. The ‘Blog’ page type is also available from the ‘Add page’ menu.

After adding a ‘Blog’ page, the site doesn’t redirect to http://localhost:8888/example/admin/pages/edit/show and simply remains on the http://localhost:8888/example/admin/pages/add/ page.
From what I can tell, the only result from this action is an ‘ARCHIVED’ page being added to the sitetree.

Have ?flush=all etc as per other suggestions to no avail and other page types are still being added fine.

Does anyone have any idea what might be going on here?

Currently using:

    "silverstripe/cms": "3.6.1",
    "silverstripe/framework": "3.6.1",
    "phpunit/PHPUnit": "~3.7@stable"
    "silverstripe/blog": "2.4.6"

While simply adding a 'Blog' page produces no observable errors, adding a generic 'Page' and changing the page type to 'Blog' produces the following error in the php_error.log:
