Help – Theme Options have disappeared

I’m not sure if it’s the result of a recent WordPress update, but i used to have “Theme Options” under Appearance on my dashboard–it’s no longer there. My theme options include an important feature that i need to update often, so this is fairly urgent. Could someone please explain the solution, keeping in mind that I am not to savvy with code etc?

Possible related, i found this post from David Sader that seems to address the issue, but either it doesn’t work for me or I didn’t do it right:

“Even a couple themes I’ve auto updated in the last couple days via the WP repository still had the ‘edit_themes’ cap.

Found ‘edit_themes’ cap in functions.php (or some other theme file that creates the menu)

This was the problem:
add_theme_page($themename.” Options”, “”.$themename.” Options”, ‘edit_themes’, basename(__FILE__), ‘wptheme_admin’);

This is the solution:
add_theme_page($themename.” Options”, “”.$themename.” Options”, ‘edit_theme_options’, basename(__FILE__), ‘wptheme_admin’);
