Hello,
A WordPress child theme is a theme that inherits the functionality of the parent theme. With a child theme, you can make modifications or add additional functionality to the parent theme. The child theme offers the safest and easiest way to modify an existing theme, whether you want to make a few small changes or extensive ones. Legenda fully supports Child Theme.
The child theme is included in the theme package. Find the Legenda-child in the package, or download from this page https://www.8theme.com/downloads/, and upload it to the /wp-content/themes/ folder.
The child theme should be activated on your site. We provide updates for the parent theme only. In case, you get a message about outdated files in the child theme after the main theme update, you need to compare files of both themes, and add the missing code to your child theme files.
The translation should be done for the parent theme only https://youtu.be/1E5L9MyQ7W4 You need child theme translation files only in case you added custom code in child theme that includes localization functions.
Also, don’t forget to backup all the files before any update.
Feel free to ask if you have any other questions.
Regards
