Problem creating config in skript

[AkroDogy2005]

I have this code:

on load:
    message "&f" to console
    message "&7(&6!&7) &7Status: &eStarting...." to console
    message "&f" to console
    if folder "plugins/AkroMuteChat" doesn't exists:
        create folder "plugins/AkroMuteChat"
    if file "plugins/AkroMuteChat" doesn't exists:
        create file "plugins/AkroMuteChat/config.yml"

But i get this problem

[15:42:14 ERROR]: can't understand this condition: 'folder "plugins/AkroMuteChat" doesn't exists' (MuteChat.sk, line 7: if folder "plugins/AkroMuteChat" doesn't exists:')
[15:42:14 ERROR]: can't understand this condition: 'file "plugins/AkroMuteChat" doesn't exists' (MuteChat.sk, line 9: if file "plugins/AkroMuteChat" doesn't exists:')

I use this plugins:
SkUtilities
WildSkript
SkQuery
Skript

I am running on Spigot 1.12.2 and wildskript doesn't work and i think this is problem how can i find a replacement for this plugin?
