Signature is not showing

Hello. I have done every step from that post: https://help.forumotion.com/t113872-signature-not-working#745616 , and still I can't see option "Attach signature (signatures can be changed in profile)" in my new post options... Is there any solution for this problem?

PS. Some of my friends have done their signature without any problems, and I can't as an administrator.


PS2. Ok guys it solved Dunno what helped but I changed forum language for english and the msg just pop up Can be closed
