GRAQ

What do you see if you go to the admin screen and click on Posts menu?

The submenu underneath should expand into ‘Posts’, ‘Add new’, ‘Categories’ and ‘Post tags’. Click on the ‘post tags’.

Try popping the clause in a variable first?

$where = "WHERE f_name = {$insert_member_data['f_name']} AND l_name = {$insert_member_data['l_name']}'"
$wpdb->update('wp_network_members', $insert_member_data, $where);

Is it that category 11 has the 9 most recent posts?

Comparing it to the codex, at first glance it looks correct:
http://codex.wordpress.org/Function_Reference/WP_Query#Category_Parameters

You could possibly try ‘localhost’ and the same username and password you logged in with. But that is a wild, wild guess.

If WP was set up the way you are implying, and you need FTP details, then that is more of a host issue than a WordPress issue.

Nice write up bigsite.

I have a little mixture of questions:
1. What is the importance of adding a trailing slash to wp-admin requests?
2. What is the relationship between rewrite /files/$ /index.php last;
and rewrite /files/(.+)$ /wp-includes/ms-files.php?file=$1 last;
3. I use just rewrite ^.*/files/(.*) /wp-includes/ms-files.php?file=$1;
Is that better/worse/same?

There is no mention of fastcgi-caching in your configs, which possibly a reason why you are not seeing as much of a performance hike as you were hoping for, as it can be comparable to supercache.

Glad to help. Don’t forget to mark the topic resolved 🙂

You should mark the topic resolved 🙂

Whenever do_action() is called, all the add_action()s get invoked.

Imagine that you want to do X when Y happens. The core team have in their function the line do_action('y_has_happened', $with_this_data);

You can write in your theme or plugin:

add_action('y_has_happened', 'my_function_when_y_happens');
function my_function_when_y_happens($happened_with_this_data){
  // Do X (with the data).
}

Hence them being ‘hooks’ they are points that allow theme/plugin writers to hook into that point.
