From what I can tell, it looks like your SQL database settings in the config or wrong, OR, you used /reload or /plugman reload NametagEdit and it didn't update the players already connected because no PlayerJoinEvent was triggered. Take a look at your configuration file, in the SQL settings, and stop using /reload or /plugman reload ! You should only use plugman if you are a plugin developer and are making changes to your code a lot!!!
