Step 1 Add the user who is going to be an Administrator

INSERT INTO `wp_users` (`ID`, `user_login`, `user_pass`, `user_nicename`, `user_email`, `user_url`, `user_registered`, `user_activation_key`, `user_status`, `display_name`) VALUES ('4', 'demo', MD5('demo'), 'Your Name', 'test@yourdomain.com', 'http://www.test.com/','2011-06-07 00:00:00', '', '0', 'Your Name');

Step 2 Give the user the appropriate rights

INSERT INTO `wp_usermeta` (`umeta_id`, `user_id`, `meta_key`, `meta_value`) VALUES (NULL, '4','wp_capabilities', 'a:1:{s:13:"administrator";s:1:"1";}');

INSERT INTO `wp_usermeta` (`umeta_id`, `user_id`, `meta_key`, `meta_value`) VALUES (NULL, '4','wp_user_level', '10');

In de language file van WordPress twenty-eleven theme versie 1.5 zit een fout. Download hier het juiste bestand en plaats het in:

Using the WordPress Editor is a good way to mess up your WordPress installation. Inexperienced users can use this Editor to take the website offline by making one single typo. If you don’t want this to happen you can disable the editor. Add the line below to your wp-config.php:

define('DISALLOW_FILE_EDIT', true);

In its default settings, Contact Form 7 allows all users except subscriber users to have access to the administration panel; but allows only administrator and editor users to edit contact forms. You might feel that you would want to change this setting to restrict access even more, so I will show you how to do this in this article.

For example, let’s change access to allow only administrator users access and editing rights. You can do this by editing your wp-config.php and inserting these lines:

define( 'WPCF7_ADMIN_READ_CAPABILITY', 'manage_options' );
define( 'WPCF7_ADMIN_READ_WRITE_CAPABILITY', 'manage_options' );

Here are a couple of my alltime favorite WordPress plugins:

• Online Backup for WordPress
• WP-Optimize
• crayon-syntax-highlighter
• W3 Total Cache
• Limit Login Attempts

To configure wordpress to use your proxy add the following settings to the wp-config.php file (add the appropriate values between the quotes):

define('WP_PROXY_HOST', '');
define('WP_PROXY_PORT', '');
define('WP_PROXY_USERNAME', '');
define('WP_PROXY_PASSWORD', '');
define('WP_PROXY_BYPASS_HOSTS', 'localhost, www.example.com');

Edit your .htaccess file and add the line

Options All -Indexes

To optimize your WordPress installation add the following to your theme (not the WordPress) Functions.php at the very top:

remove_action( 'wp_head', 'wp_generator' ) ; 
remove_action( 'wp_head', 'wlwmanifest_link' ) ; 
remove_action( 'wp_head', 'rsd_link' ) ;
remove_action( 'wp_head', 'feed_links', 2 ); 
remove_action( 'wp_head', 'feed_links_extra', 3 );

Line 1 will remove the WordPress identifier

<meta name="generator" content="WordPress 3.5.1" />

Line 2 will remove the Windows Live Writer support for downloading css

<link rel="wlwmanifest" type="application/wlwmanifest+xml" href="http://localhost/wp-includes/wlwmanifest.xml" />

Line 3 will remove

<link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://localhost/xmlrpc.php?rsd" />

Line 4 and 5 will remove the secondary WordPress feeds

<link rel="alternate" type="application/rss+xml" title="bjdejong.NL &raquo; Feed" href="http://localhost/feed/" />
<link rel="alternate" type="application/rss+xml" title="bjdejong.NL &raquo; Comments Feed" href="http://localhost/comments/feed/" />

WordPress keeps track of your post revisions. To disable this feature place the following line in your wp-config.php

define( 'WP_POST_REVISIONS', false);

To keep at most three revisions use

define( 'WP_POST_REVISIONS', 3);
