Edit your functions.php, it seems you added extra space anywhere at the end of that file when you edited it.
AND that <?php show_flickr_feed_gallery(); ?> shouldn’t be in your functions.php file, instead add it in your index.php, single.php or page.php template files (where you want the widget to appear)

It’s not loading the HTML heads correctly (check the html source of that page, it lacks doctype declaration, html, head and body tags).
Check if you got your index.php template fuxored (by not declaring get_header() ) or if you have the header.php template in your theme folder.

probably you need to edit your:
index.php or/and single.php templates adding the bit of code you use on your page.php template to ouput the custom fields values.

File and folder permissions:

Hosting: https://ftp.your_domain.com
Name: your_ftp_name_account
pass: your_ftp_pass

Usually your main account name and pass in your hosting control panel its your ftp pass and name (not your name/pass in wordpress), though it could be different depending on the hosting company; may be you need to setup an FTP account.

I see you got it working now ??

check your single.php template code in your them folder. It seems a <div> or element are not properly closed.

First, this is a community driven forum; people tends to answer what they know and when they have time.
Second, search is the key:
A simple search “lost password” on Codex gives this, try the first link:
https://www.ads-software.com/search/lost+password?documentation=1
Third, provide enough info: wordpress version? url?

Did you read the link ClaytonJames gave you?
There you can follow the phpMyAdmin path.

in your page.php template, where you want the links to your child pages appear:

<?php if (is_page(ID)) {
wp_list_pages('child_of=ID');
} ?>

Where ID is your page ID number.
If you have more pages with childs add more “else if”

<?php if (is_page(1)) {
wp_list_pages('child_of=1');
} else if (is_page(2)) {
wp_list_pages('child_of=2');
} ?>

Note that numbers here are mere examples, you should put your page parent ID.
More parameters for the wp_list_pages() template tag:

This is something I would love to see… for example, if you have a blog with different languages you could share the same attachments (images, files) for the same posts/pages in different language

And, commenting on this, if wp devels are going to fix this I would get rid of the hardcoded inline style too.

Probably it has to do with your themes/yourtheme/category.php template.
Load the default theme and check if it does the same thing.

It always amazes me why people don’t even bother to search at “codex” (docs):
https://www.ads-software.com/search/exclude+pages
there you go, the first result… easy and fast

https://yourdomain/wp-login.php

The text inside your footer <div> lacks <p></p> tags, that’s why your css is not working, anyway add text-align: center; to #footer and you are done

Edit:I’m being very slow today
