Hi Marie Jane, I have managed to get Koha partially running again, meaning that it is fully functional, but for now it needs a manual entry in the terminal. I am waiting for somebody to come up with an answer. Basically it's exactly what I thought it was, but  so far no easy solution. Sigh. Life's never easy, is it? Anyway, in case you need to work with it; After you have started the computer, open a terminal (click on the little foot at the left bottom, the top of the list is accessories, from there you can open a terminal, basically a text window) In the terminal, type: sudo zebrasrv -D -f /etc/koha/koha-conf.xml (enter) (if it asks for a password, it will be: handsoff) Now it will work. Hopefully I can get it fixed tomorrow, so you won't need this. Marty
