Never change theme files – use Theme Settings or create a child theme.
If you change theme files, all your changes will be lost with updating the theme, as all theme files are replaced everytime you update. So before just running into the code, always…
Check the following before:
1. Theme Settings:
First always check the theme settings page if there’s an option for that. If so, it’s done!
Often you can do it just via CSS. For example just hiding things, too. You can add your custom CSS styles into the CSS tab in the theme settings page. This way you stay update safe. Yay!
3. Child Theme:
That’s the clean and solid way for your custom code. Create a custom child theme of Custom Community and stay update safe! More info in this How To:
