Theme panel does not work

I am building a magazine with the Newspaper theme, trying to make changes in the footer using Theme Panel, and it does not work. I tried disabling plugins to see if that’s the problem and its not, my theme is fully registered, cleared cache, and nothing, my Theme Panel does nothing. So what’s the problem? I wat to change my footer to a black footer with white fonts and nothing is working, and I want to make changes to my header. I am using the Urbanobserver template. Thank you.
