Thank you, hope someone can help me

 

@Ketchup112 Please post your groups.yml in pastebin.

 

found character '\t' that cannot start any token
means
"You used a tab at least once here"

Purge the tabs for proper spaces. And as bwfcalshy says, pastbinning the whole file will help with other issues - but get rid of the tabs first.

 

here <------ is my groups.yml

 

Line 27-42 are against the 'wall'. They need to be spaced (Not using TAB) 4 away matching the other nodes.

There is an error on line 27. It may be TABed instead of spaced.

Config Evidence:
line 27, column 1 - essentials.sethome
