Add Dashboard Columns Plugin

Enable Dashboard Columns in WordPress 3.8 or later

1. In your WordPress admin panel, go to Plugins > New Plugin, search for add-dashboard-columns and click “Install now“
2. Alternatively, download the plugin and upload the contents of add-dashboard-columns.zip to your plugins directory, which usually is /wp-content/plugins/.
3. Activate the plugin through the ‘Plugins’ menu in WordPress.
4. Go to the Dashboard and change the layout columns inside the Screen options.

What meta delete?

This plugin delete screen_layout_dashboard and screen_layout_dashboard-network.

Why not delete meta-box-order_dashboard or meta-box-order_dashboard-network?

Basically because I do not consider it necessary, and may be an established order has not been changed and the number of columns.

Is possible disabled for a specific user or network site?

Yes, use the add_dashboard_columns_enabled filter to switch.
Note: It does not remove any configuration simply prevents to fire the hook.

I activated it but it does not show the layout, what happens?

The most certain thing is that the assets are missing, since they are checked to avoid UX issues.

Needs support?
