Seems to be a theme configuration issue.
Can you check if you've got a file called project.yml in your /usr/
local/www/symfony/steercms/config folder?
There needs to be a paragraph that looks like that:
themes:
enabled: true
items:
default:
title: SimplyBlue Base
description: Standard theme for frontend
file: "steerCMSSimplyBlueTheme::layout"
thumbnail: /themes/steerCMSSimplyBlueTheme/images/
thumbnail.png
- title: GreenerPastures Base
description: Steer CMS based theme, don't forget to eat
your greens
file: "steerCMSGreenerPasturesTheme::layout"
thumbnail: /themes/steerCMSGreenerPasturesTheme/images/
thumbnail.png
That file defines the theme configuration and some other project
specific parameters.
As for the 404 errors in the CMS admin. Can you add "backend_dev.php"
to your address like http://localhost/cms/backend_dev.php and send
me the error messages displayed after that so I can check it?
