Worth a shot. Or, try this: backup and delete (or just rename) your restrictions.txt limits.txt loadouts.txt files in data/ulx, startup server, add some test values using the menu, run "ulx print all" in your console as an admin and it should print all the values you added, then restart your server and run the command again, it should print the same thing if it is actually loading the files.
Also, are you getting any lua errors?
