I am using essentials and permissionsex so far, and permissionsex wont load I get this massive list of errors.

EDIT by Timtower: merged posts

 

08.03 21:39:47 [Server] INFO in "<string>", line 44, column 1:
08.03 21:39:47 [Server] INFO found character '\t' that

This means the parser found a tab character in your yml - tabs aren't allowed, all indentation needs to be spaces.

 

thanks guys!
