1. the permission: BattleKits.sign.use does not work when I place the permissions node in Group Manager, players still cant use signs to get kits.
2. Players are still dropping items on death: You need to explain this better in the FAQ, how do I set it up properly, do I set enable-restrictions: true in the global.yml and then give them the:

BattleKits.bypassRestriction.disable-dropping-items
BattleKits.bypassRestriction.disable-crafting
BattleKits.bypassRestriction.disable-pickup-items
BattleKits.bypassRestriction.disable-block-place
BattleKits.bypassRestriction.disable-player-drops-on-death
BattleKits.bypassRestriction.hide-death-messages
BattleKits.bypassRestriction.disable-mob-xp
BattleKits.bypassRestriction.disable-block-xp
BattleKits.bypassRestriction.disable-block-break
BattleKits.bypassRestriction.disable-inventory-click

Or do I leave it set toenable-restrictions: set to false and still give them the bypasses above?

1. Some kits will not show up, I find that when I add anymore than one enchantment to any type of armour, the kit won't work and no armour shows up.

REQUEST 1: How about you take time to write a better layout for the plugin webby it is all over the shop and not very clear in instructions, this is very evident by the amount of problems listed here in GitHub, if it was more clearer them we might not have so many questions

REQUEST 2: Try and be on more often so we can get help sooner!!

UNFORTUNATELY: I find that this is one on the most frustrating plugins I have tried to use, I like the layout but the instrustions are out dated....example:

Last time I looked I didnt have any of the settings in my kits.yml

settings:
once-per-life: true
# Whether or not players can only use kits once per life
no-auto-update: 1
#Uncomment to disable auto-update
hide-death-messages: false
# Whether or not the vanilla Minecraft death messages are hidden
disable-dropping-items: false
#Whether or not players can drop items (using Q or dragging out of their inventory)
disable-player-drops-on-death: false
# Whether or not players drop their items on death
disable-crafting: false
# Whether or not item crafting is disabled
disable-player-xp-drop: false
# Whether or not players drop XP on death
disable-mob-xp-drop: false
# Whether or not mobs drop XP on death
disable-block-xp: false
#Whether or not XP is given on block break (e.g. coal)
disable-inventory-interaction: false
# Whether or not users can move items in their inventory
disable-pickup-items: false
# Whether or not users can pick up items
disable-block-break: false
# Whether or not players can break blocks
disable-block-place: false
# Whether or not players can place blocks
show-kit-info-on-respawn: true
# Whether or not kit information is shown on respawn
kits:
archer:
active-in: "'world','word_nether','word_end'" # Change to "all" for all worlds
commands: # Executed on kit give
- 'tell Enjoy your kit :)'
on-give-message: '&cYou're now an archer' #Message displayed when kit is delivered
items:
helmet: leather
chestplate: leather
leggings: leather
boots: leather
helmetColor: '#FF0000' #Dyes the armour

Closing due to inactivity.

If you set enable-restrictions to true, nobody will be able to do anything - it's then up to you to give the bypass permissions as necessary.

Yeah, it's all permissions based now - you won't see those settings in your config.

As well as the sign permission, they still need the kits permission unless you tell BattleKits that signs allow permissions bypassing.

There's most likely an issue with your config if enchantments aren't working. I'm not sure if BattleKits supports multiple enchantments, but give me your config and I'll take a look.

I'm no longer maintaining BattleKits personally (at present, anyway). Take a look at LiteKits for a more extensible, lightweight plugin.
