This happens when your existing files are owned by a linux user, say root and your are running the cron jobs as another user, a web user for example, and the second user does not have enough permissions to overwrite existing files, since they aren't owned by it.
I would check and make sure all your mailwizz files are owned by the same user under which you have added the cron jobs.
