Hi James, The NullPointerException seems to happen here: https://github.com/DSpace/DSpace/blob/dspace-6_x/dspace-api/src/main/java/org/dspace/content/CommunityServiceImpl.java#L120
This is a very odd error, as it seems to throw an error on the Site object, which is an object that doesn't actually exist in the database, but in the API itself (i.e. it's a conceptual object that should *always* exist). This is very odd behavior, so it makes me wonder if you upgraded from a previous release (4.x or 5.x), and accidentally have some old API/JARs sitting around (which could cause conflicts with the DSpace 6 APIs). This shouldn't be occurring on a fresh installation. I'd recommend trying a fresh install either in a different directory (on same server) or perhaps on a different server. I've never seen this behavior, and it almost seems like you have conflicting JAR files in place. You also could closely check your logs for other errors...It's possible there are other related errors here that could give clues. See also: https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error Good luck, and feel free to report back to this list with whatever you find.
