Hello again, sorry to keep bugging this list. I upgraded to v. 3.18.06 a few days ago and was directed to edit koha-conf.xml and zebra-biblios.cfg file. As far as I can tell, I did that correctly and no longer see warnings about that in koha client>about koha>server information. However, I was still getting errors when I tried to restart zebra, and at that point my entire catalog became unavailable. I have double checked those files I edited, and have just tried restarting zebra as root (thank you Robin). Here is what I get: Zebra does not appear to have been running for instance library. Starting Zebra server for library ... but Zebra won't start. I should mention that previously, I tried rebuilding the index, and that did not work either. In fact, I tried rebuilding, then I read I should not rebuild as root (see http://wiki.koha-community.org/wiki/Fix_zebra_permissions), so I rebuilt as user after following those instructions, then tried restarting zebra again as root -- same error above. I am unable to start zebra using koha-start-zebra or koha-restart-zebra. So I am still looking for advice. If anyone still suspects my koha-conf.xml or zebra-biblios.cfg files, I would gladly send you the printout from those or snippets from them. Thanks so much! Amy
