The pokestops do not spawn naturally. which is the least of my worries bc there is a command to spawn them. the main problem is that when i do spawn them, nothing appears. its invisible. also i tried putting items in the pokestops in the config but as soon as i place the pokestops i dont get anything... maybe im doing this all wrong but it could also be a bug.

Pokestops are not supposed to spawn naturally. Your particles are most likely off. Pokestops uses Minecrafts default particle system therefor if you have them disabled in your Video Settings, you will not see them.
