Okay, allow me to correct my statement:

Paste the full class(es) and full stack trace in code tags.

Sorry for polish code

 

Edit posts, remove text, repost using www.pastebin.com.

 

Without code tags it's basically unreadable. You could also post it on http://www.pastebin.com or http://gist.github.com

 

Solved

I forgot to add .yml

Sorry for problem
