APOC - Loading from JSON

Unable to load json using apoc. It gives error while restarting the DBMS if the below statement is added:
apoc.import.file.enabled=true

@abhijeet.talele

a. what version of Neo4j?
b. if Neo4j will not start it would be helpful to see the bottom/tail of logs\neo4j.log

Where did you add the line? neo4j.conf? You need to create a file in the configuration directory called apoc.conf and place that line it it. It should work after restarting the db.
