This issue is caused by the code customizations, please try removing it (if you have a developer who added this code you can contact them so they can resolve these issues). By default, the functions.php file looks like this Awesome Screenshot

Also, please don’t keep customizations in the theme or plugin files, any update will erase these changes. You can keep custom code snippets via the Code Snippets plugin or in the child theme’s functions.php file (if you create a child theme for overriding specific template parts).
