Welp,i read a lot of things which should fix that,but nothing works,actually I already reloaded Citizens plugin,downloaded Vault,so i have no idea how to fix it.
When i trying to use some commands from Citizens,(excluding /help) there's happening some crap,and i don't know what causes it:
[An internal error occured while attempting to perform this command]
How to fix that?
UPD:Uh oh,maybe the plugin needed to be updated directly in aternos plugin list?
