Hi Dek, sorry if I write again.
I solved the above problem by itself, your colleagues have never responded.
I noticed that in my About page (http://www.ibrsistemi.com/new/about-us/) shows “by IBR SYSTEMI, September 29, 2014” I have tried both options in wordpress than in the your site but could not find how to remove it.
I wanted to avoid changing the code.
Can you help me again?
Thank you very much
