You can see some errors thrown throughout forum. Maybe some filesystem permission issues as I don't think flarum would normally throw errors that would reveal underlying directory structure, unless you have debug mode on. Anyways, someone else here could probably better decipher than I could so I'll leave it to the experts 😉
