I’m having the same problem since upgrading to 4.3. I can still edit in the Text tab (raw HTML) but Visual tab is blank and is missing the normal set of edit controls.

I have another site as well that’s fine, so I suspect that some difference between the 2 sites would explain why 1 has the problem. No idea where to look though.

Help!

tiffdotc: Did you update the twentytwelve theme? If so, the h3 tag needs to change to button; otherwise navigation.js won’t find the menu, since it now looks for button. Your code sample shows an h3 tag still; try changing it to button and test it.

jennymg: You’re welcome! ??

We use a twentytwelve child theme on our site and it too stopped working on mobile devices recently (within the past 2 weeks) (Menu button present but not working). I banged my head against the problem for a while and finally figured it out:

We have a custom header.php that was a copy of the stock one with code added for our SSL certificate but with no changes to the navigation. We haven’t changed it in a while (sometime in June I think). Our header.php, and the original from twenty twelve until very recently used an <h3> tag for the Menu button. The newest version of the theme uses <button> instead. The code that updates the toggle is in navigation.js, which we did not touch in our child theme, but it too was updated to look for a button object instead of an <h3> like it used to.

I figured it out by running the site in the Chrome debugger and saw navigation.js look for a button object that wasn’t there. I then checked the theme files and compared to a backup from July and discovered the change.

Anyway, I fixed it by changing the <h3> to <button> in my child theme and everything works again.

It appears that there was a theme update on or about 9/8/14 that introduced the problem. I will pay closer attention to theme updates from now on.
