@cmb:
To anyone who runs into this problem in the future, you can use Diagnostics -> Edit file to open /etc/inc/pkg-utils.inc and towards the top of that file you will see several require_once lines. Add this line with the ones that are there:
require_once("config.inc");
then save the changes and that will fix it.
Once the next official 1.2.3-RC, or shortly after 1.2.3 release is out, you'll want to re-flash with the new nanobsd embedded, which will also fix the problem. Current snapshots also do not have this problem, some that shipped from Netgate with images we provided them.
Thank you CMB. That indeed did fix my errors on the CP page.
Looking forward to 1.2.3 stable but this RC seems to be now working for me well.
Thanks again.
