Hello,
A few days ago our NopAccelerate plugin couldn't reach our SOLR install, it just gives the error "HTTP Status 503 - Server is shutting down or failed to initialize" If I look at the tomcat logs, specificially the solr log, I see the error:

INFO  - 2015-02-25 15:28:27.662; org.apache.solr.servlet.SolrDispatchFilter; SolrDispatchFilter.init() done
INFO  - 2015-02-25 15:30:06.059; org.apache.solr.servlet.SolrDispatchFilter; SolrDispatchFilter.init()

ERROR - 2015-02-25 15:30:06.561; org.apache.solr.servlet.SolrDispatchFilter; Could not start Solr. Check solr/home property and the logs

Where [messagehub] is the name of the core we were using. No one on our team has touched the SOLR installation since we installed NopAccelerate with your install guide and Google has provided no info. Any ideas on how to fix this?
