Permissions do not work?! I've added the correct one and the commands only let me use them on ops

- playtime.use

is there something else? like no one can do it even with other perms. using the most updated version and im running bukkit 1.8.7

.... anyone can help or?

Please paste your entire permissions.yml, the permissions do work, it's very likely that you have groups or permissions assigned incorrectly as a whole.

Every other permssion is correct and works for all other plugins here is the guest rank just some permssions that all work besides playtime ones
permissions:
- playtime.use.top
- dungeonbuilder.dungeons.start
- magicspells.rank.Novice
- playtime.use
- noitem.nocraft.woodensword
- keepitems.keepxp
- keepitems.keep

Please, provide the full file. That alone provides no context.
