In nodebb's case it will just need the A (or E... which will be nginx. Don't ask me why the E stands for nginx, as that is how they named the stack. Maybe because it is pronounced engine-x) and the M... for mongodb
Does Nodebb use Apache? When I try to view my forum on my VPS it loads an apache page.
Nope, your vps uses Apache. Nodebb has no proxy built in. But supports Apache or Nginx.
Thank you for the reply, I appreciate it. I must have installed it a while ago and I currently don't even remember doing so. Thank you.
