I’m worried. Because this is my first web with wordpress and I didn’t know I had to used a child theme. I used the demo of “church” X theme. I changed many things, but the template is the same. Will I have problems in the future? Is It easy to change the web now to a child theme? Tips?
Since you are starting up and if you have made any core changes we recommend you to migrate them into child theme. If you have already made the changes into core files, then you need manually post them to child theme.
