I am trying to disable the twentyeleven theme options page so as to introduce my own. My problem is similar to this one, but this wasn’t the solution for me. I tried commenting out this argument on line 86, but to no success:
Do not edit the Twenty Twelve theme. It is the default WordPress theme and having access to an unedited version of the theme is vital when dealing with a range of site issues. First create a child theme for your changes.
