Hi,
We have checked your site and found that the following issues can’t be caused by theme update because there were no such changes related to the header columns or widgets.
1. To fix the menu alignment in the top bar you need to change the layout of the top bar row in header builder settings (check the screenshot https://prnt.sc/cpyeykL8YHAB)
2. Footer widgets cant disappear after theme update, but they may disappear after switching to another theme and unfortunetly in that case, they can’t be restored. You need to manually recreate them from a scratch.
Kind Regards
