[Plugin: White Label CMS] Does not save changes for "Dashboard" and "Admin"

This was a first time installation of the version 1.4.3.

Changes in the “Branding” section are being saved normally. However, when I make changes under “Dashboard Panels” and “Admin Settings” and click on “Save changes,” it will not save the changes. Opening up Dashboard Panels and Admin Settings shows the old default setting again. And true enough, when logging in as a Contributor user the Dashboard appears as per the default settings and not with the settings I tried to save.

I would really like to use this plugin… :-/
