The deprecation notices are due to the plugin not being fully compatible with the latest PHP version you’re using. * These deprecation notices won’t prevent you from creating a child theme, but they can cause issues down the line if not addressed. Here are a few steps you can take: - Ensure all your plugins, themes, and WordPress itself are up to date. The plugin developers might have already fixed these issues in the latest updates. - If the issue persists after updating, you might want to contact the plugin developers directly. They can provide the most accurate information about when they plan to make their plugin fully compatible with your PHP version. - In the meantime, to suppress these notices, you can disable debug mode in your wp-config.php file. Find the line that says `define('WP_DEBUG', true);` and change it to `define('WP_DEBUG', false);`. Remember, this is a temporary solution and the underlying issues should still be addressed. * I hope this provides some clarity on the matter. If you have any other questions or if there’s anything else you need assistance with, feel free to ask.
