Customizing Current Theme Templates
- Create a child theme
- Copy your active theme’s single.php file
- Paste it into your child theme.
- Rename it to: single-epkb_post_type_1.php
- In single-epkb_post_type_1.php remove the sidebar code and apply any CSS that will fix any layout issues.
From here you will need to edit this file according to your theme.
Always remember to back up your website before making any changes or better yet, make the changes on a staging site where you can test your changes without affecting your production site.
