Restore breaks admin page?

I’ve seen this twice now. In the process of debugging an incoming trunk problem with my provider, I got things so messed up, I decided to restore from a snapshot I took. When the restore is complete, going to the admin page leaves me with a completely blank window (and firefox says “Done” at the bottom left corner…) I ended up (both times) doing an install_amp again and that fixed things…) This is asterisk 1.4.14 and freepbx 2.3.1.

(BUMP)

no one else has seen this?
