I added this flag to worldguard but it still doesn't work unless I'm OP.First Of all you shouldn't post your question here.Second this is what you need to do: I think you have worldedit and worldguard haven't you? If you have, this will work: Download worldguard version 6.0(It only works with this version) then you need to do this ingame : /rg flag __global__ lighter allow
Sorry for posting on the wrong plugin page! I will post it on the correct plugin page.
Solved by editing the WorldGuard: block-lighter: false
Not sure why the flag wouldn't work. Thanks for the tip
