What version of unraid are you using?
Does the plugin show the app started, says "running"?
I just ran a test and both versions work, so it must be a problem with either your config file or the db. If it's a problem with the DB, there likely isn't a way to save it, but if it's just a config problem its fixable.
First things first, set the run as user to 'root' and hit apply, then start the app. After, set it back to 'nobody' and hit apply, then start it again. That will reset the permissions on the folders. Does that start it? also, depending on how large your DB is, you need to give it a little time to start after it says 'running'. Some large db's can take up to a minute.
