3.3.8 destroyed design + hamburger menu not working anymore

Wow, I’m not happy with this. The given website updates automatically, so I noticed it this way, but I’ve three other websites based on this same design, so I have to recover them all after updating to 3.3.8.

In particular the mobile view is seriously destroyed. I need to look into that thoroughly. But the most serious problem is the hamburger menu in mobile view. It is not working anymore.

Was it really necessary to change this much in the code files of this new release? My child theme is kind of worthless now, I’m afraid.

Btw, sorry for all your efforts, but I don’t really like the changes.

• The top menu is no longer plain sticky anymore and that’s not very handy. Now every time you have to scroll up a bit, to make it visible again. In my opinion that’s not great usability.
• Making the sidebar temporarely sticky when scrolling down, is not very handy either. It could be a nice feature when you have a very short sidebar, but when you’ve put a lot of information in that sidebar and you want people to see it all as quickly as possible, it’s just frustrating that it is ‘hanging’ this long.

Could you make these changes optional please? That would be great.
