Oh, yes, I’ve run into this. Compare the header.php of the updated 2012 theme to the one in your child theme. Look at the markup around the menu toggle. I believe it changed to a “button” (though my memory is hazy on this). In any case, compare the two files where the menu toggle is defined.
Oh, wow! Worked like a charm. Thanks, Steve!
I just changed:
<h3 class="menu-toggle"><?php _e( 'Menu', 'twentytwelve' ); ?></h3>
into
<button class="menu-toggle"><?php _e( 'Menu', 'twentytwelve' ); ?></button>
Oh wow, I ran into this problem just now and this solved it for me too. Thanks for saving me a crap-ton of time trying to figure it out on my own!
Hello..
Is it any idea how I can hide the mobile nav and show just normal desktop menu on any device?
Thanks
