How can I make sure my custom changes don’t do to waste with new updates?
It’s always a tricky thing to support custom changes for buyers. The thing I recommend the most is to make backups of your files!
Next, rename the new themefolder from “therestaurant” to something like “therestaurant3” or “therestaurant_new”. The name doesn’t matter much, but it will allow you to install the old and new version next to eachother
Now you can re-apply the changes you made to the old version way easier!
