Erick,

Don't worry, I'm equally as sceptical of the situation... But my client
doesn't have access to the server and I haven't been on in months... So
unless my web host went tinkering :P Could an update have caused an issue? 

If I type in:

cd $SOLR_INSTALL

as per the README file, I'm taken to /root. This doesn't seem right, does
it? In my Solr Admin, the CWD is listed as /opt/solr-6.0.1/server and my
core instance is at /var/solr/data/comox_core

I tried going to the contrib/extraction/lib folder and running that find
command, but I just got:

bash: jar: command not found

a bunch of times (once per .jar file, I assume).

Another interesting thing is that when I opened my Solr Admin this morning,
I was shown the following error:

SolrCore Initialization Failures
Hacked:
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
Could not load conf for core Hacked: Error loading solr config from
/var/solr/data/new_core/conf/solrconfig.xml

I have no idea where this "new_core" bit is coming from... I've only ever
had one core (comox_core).

I really appreciate any help you can give!
