Good, back to twentyfifteen/functions.php …

Do you have this part exactly? if so , on what line numbers?

/**
 * Twenty Fifteen functions and definitions
 *
 * Set up the theme and provides some helper functions, which are used in the
 * theme as custom template tags. Others are attached to action and filter
 * hooks in WordPress to change core functionality.
 *
 * When using a child theme you can override certain functions (those wrapped
 * in a function_exists() call) by defining them first in your child theme's
 * functions.php file. The child theme's functions.php file is included before
 * the parent theme's file, so the child theme functions would be used.
 *
 * @link https://codex.wordpress.org/Theme_Development
 * @link https://codex.wordpress.org/Child_Themes
 *
 * Functions that are not pluggable (not wrapped in function_exists()) are
 * instead attached to a filter or action hook.
 *
 * For more information on hooks, actions, and filters,
 * {@link https://codex.wordpress.org/Plugin_API}
 *
 * @package WordPress
 * @subpackage Twenty_Fifteen
 * @since Twenty Fifteen 1.0

Good morning @pwdiane
Are you sure about twentyfifteen/functions.php ? … It appears to be duplicate of responsive/functions.php ?

I don’t think you’re missing anything, fairly certain it is responsive exactly as intended. You can read more about it here: https://wordpress.org/themes/twentyfifteen/

Will a restore lose content?

Yes, a database restore will lose any content additions and/or edits done since the backup was made.

How about plugins I’ve added?

A database restore would not cause plugins be lost, however they might contain malware code and probably should somehow be analyzed and cleaned

Remain calm and carefully follow this guide. When you’re done, you may want to implement some (if not all) of the recommended security measures.

Very Good, Yes, the Screen Options … I see now you had the show_in_menu and show_in_nav_menus both true. Please mark the topic resolved?

Is it possible? Yes

Is it easy? No, not at all, unless you understand CSS media queries and CSS positioning and whatever you did with code from comment 4.

Except for between 768 to 800 px screen width, Your menus appear to me properly visible. The location of the mobile menu top right is a generally accepted convention. It’s called a “hamburger menu”, two slices of bread and the hamburger patty in between!

If you’re using p2 as a parent for your child, all the js and inc files will be there and available.

For a new parent, To begin, I would just keep all of P2/js and all of P2/inc …

Sorry, I can’t speak at all to the P2 functionality, it’s not mine. P2 is by Automattic, the same folks who operate WordPress.com. I would suspect P2 is authored by @matt himself.

Anything more should be here I believe: https://wordpress.org/tags/p2?forum_id=5

OK good back to the root folder …

if present /index.php rename to /index.php.bad

and

create file /index.html with text contents ” this is /index.html ”
