Your forum may work, but has no security, anyone can login and delete/steal the database. You need to setup your redis so that it has a password, and that it restricts access to localhost.
@yariplus thank you so much.
I just move my project to another machine.When I run the command './nodebb start',I got this problem.
@swang I suspect that is due to the changes that began in 1.4.3: https://blog.nodebb.org/introducing-the-build-system-in-v1-4-3/
@swang which theme are you using and what version of the theme?
That is a warning. That should not be causing issues for when you visit your site. Check for other errors in the nodebb log and in your browser console.
