I use google translator!
Hello aternos team! 
I had a problem on a server with a magma core, the problem is that the PermisionsEX plugin is not possible to download because no suitable version was found!
because this plugin supports up to 1.11, but it's a lie! it works great on all versions above 1.11+
I ask you to remove the inscription so that it can be downloaded!
