Hello,
First of all, check if everything is ok on the staging site. Because once you migrate to production everything will be the same. So, it’s important for you to fix everything on the staging site first, and then depending on changes that we’ll make I’ll be able to guide you. Or better to allow us to do that quickly and good to avoid problems. And just don’t skip a lot of major updates in the future. Then you’ll be able to update the theme by yourself in the future, without our help like this time.
Regards
