• Did you enable permissions in the config? (See this)
• Did you add all permissions on your spigot (fork) server?
• Are all permissions added correctly (spelling mistakes, context mistakes, group mistakes)?
• Use only lower case permissions. Some systems cannot handle upper case permissions.
• Did you add all needed additional permissions?

Try my example list if you still get issues for setting up your user permissions

All permissions are enabled be default if the plugin has to create a new Config.yml file. This means, that every use permission will be activated and users without them cannot use them.
Permissions can be disabled in the Config.yml.

Options like max player warps will be configured in the PlayerWarpConfig.yml then.

• Teleport costs: warpsystem.bypass.teleport.costs
• Teleport delay: warpsystem.bypass.teleport.delay
• Bypass max player amount: warpsystem.bypass.teleport.maxplayers
• Cooldown: warpsystem.bypass.cooldown

Every feature has its own use and modify permission to provide 100% customization. All permissions are choosen in the same syntax.

• Use permission: warpsystem.use.<feature>
• Modify permission: warpsystem.modify.<feature>
• Additional permission: warpsystem.<feature>.<additional tag>
