FAQ

Can I get the plugin for free?

Please refer to this section.

Support for 1.8 and lower versions

Please DO NOT ask me to support 1.8 ever. This version is extremely outdated, it's more than 7 years old.
Almost 40% of the plugin features will stop working on this version and it's incredibly hard to maintain.
The only reason 1.9 and versions above are supported is because they're just easier to maintain. I always recommend using the latest Spigot version. The plugin doesn't guarantee that the old versions will always be supported.

If your reason for not using 1.9+ is the PvP mechanics, use OldCombatMechanics.
Another excuse I usually get is that, "1.8 is more stable". 1.12 is better than 1.8-1.11 in both performance and stability aspects. The only reason it uses a little more resource is because of the newly added features which is completely normal.

Why players can't pickup turret and structure items?

They're probably in creative mode. Players cannot do that because they'll be able to duplicate the item in creative and use it everywhere. If you like an admin to bypass this, give them kingdoms.creative.pickup permission.

Why aren't my turrets shooting?

Make sure your turrets have enough ammo. You can buy ammo for your turret by right-clicking them and pressing the ammo button.

Duplicated Chat

If you want to use another chat plugin other than kingdom's built-in system, you have to go to config.yml -> chat -> global-channel -> format -> false
Another thing you can do is to parse kingdom chat formats as placeholders to use in other chat plugins (if they support the use of normal chat channel AsyncPlayerChatEvent) by going to config.yml -> chat -> parse-as-placeholder -> true
Most people use another plugin because the support hovering on messages. Kingdoms also support that too if you want to use it.

When breaking the block underneath turrets, they still work.

This is not a bug. Those block is not required for the turret to continue working. It's just a practice to encourage players to put their turrets on specific blocks. You cannot force the turrets to stop working after the block is broken, because it can lead to server lag when used excessively.

/k disband doesn't work (error)

This is a 1.15/1.16 Spigot bug and I can't fix it, Spigot is supposed to do it. This happens to any GUI that has a hopper (and a few other special types) inventory. You'll have to update your server either by running BuildTools or getting a direct download from Paper. Please avoid any other websites or forks. They're mostly outdated as well and won't fix the issue.
