Greetings! I am having trouble creating a child theme, I have never done it before. I asked in your support chat room and they said the following:

Joseph, we can definitely provide a more detailed explanation on how to do it if you create a support ticket:

and we can setup your first child theme for you, which I think should help you get more comfortable with it :slight_smile:

The reason I am trying to set up a child theme is because I received the following message from other development:

Oh, ok. You need to update to the latest version (2.7.4).

Before you do that you should create a child theme and move all your changes over because when you update, any change done to the theme files will be lost.
