Hello, this issue indeed lacks some information but, from what I can read, it looks like your permission manager plugin is not capable of handling primary groups, which is a requisite of ZHorse.
Try with another permission manager (it can be as simple as BukkitPermission, for instance) and see if it happens again.

@Zedd7 Thanks very much I will try this when we get home, I'll let you know how it goes
