Global Configuration of Joomla CMSSite MenuThere are settings that apply to all individual pages and to your server. All of these settings are summarized in the Site menu. 
Figure 4.7: Site Menu Global Configuration The Global Configuration workspace administers changes in the configuration.php file. It contains vitally important pieces of information like the access details for the database server. This workspace is divided into ten tabs: 
Figure 4.8: Site Site The Site tab contains parameter switches related to various settings concerning your entire website:
Site Offline: This gives you the option of turning off your site while, for instance, you are carrying out changes to your site and you don't want visitors to track your development progress.
Offline Message: The text entered here is displayed on your site when it is switched off. If you want to use another logo, you can save one with the name of [joomla]/images/logo.png. Otherwise, you have to customize the path accordingly. Figure 4.9: Display notice when the site is switched off System Error Message: Here you can type in a message that is displayed if no connection can be established with the database server.
Site Name: This is the name of the site that you entered during the installation.
Show UnAuthorized Links: You have the ability to display individual pages only to registered users. It is possible that these pages get linked from a public connection. If you choose Yes, these links are displayed. When a visitor clicks on such a link without logging on, a message appears announcing that this is a protected area that requires registration.
Allow User Registration: This allows you to select whether you want to permit users to do their own registration or not. If you operate a company site, you could set up user accounts for your coworkers, but forbid them to create their own account. On the other hand, with a community site, it is desirable for users to log themselves on.
Use New Account Activation: In order to protect yourself from automated programs that can create 20,000 user accounts on your site, you can ask for separate activation. The user gets an automatic email sent to the address given by him or her. There is a link in this email that activates the account through websites. After activation he or she can log on normally.
Require Unique Email: Choose whether each email address is to be used for one account only.
Debug Site: Here you can switch the site into debug mode. After activating this function, the database queries of the site are displayed. In order to generate a single Joomla! page, 83 database queries are required, as shown in Figure 4.10: 
Figure 4.10: Debug Mode with Database Queries Default WYSIWYG Editor: WYSIWYG is the abbreviation for "What You See Is What You Get". The term originated at the beginning of graphic user interfaces, when it first became possible to see how the printed document would look as you typed the text into your word processor.
On the Internet, you normally fill out forms with no formatting ability. Formatting is done by HTML tags or program-specific mnemonics. A WYSIWYG editor is user-friendly, since you have to click an appropriate icon, just as when formatting text. This editor is automatically invoked for the text fields that require formatting as illustrated in Figure 4.11. It works with all the usual browsers: Figure 4.11: WYSIWYG EditorJoomla! also offers the ability to integrate other HTML editors. The default editor, TinyMCE, is used at this time. You can find out more about it from http://tinymce.moxiecode.com/.
List Length: Lists, like news and links, will crop up every now and then on your site. With this, you can set the default number of entries that such a list can have.
Favorites Site Icon: Every site can offer the surfer a favorite-site icon (favicon). This small picture is displayed to the left of the URL, as well as in the bookmarks of the browser. This works really well in most browsers: 
Figure 4.12: Favicon in Firefox In Internet Explorer, however, this works only under certain conditions (see Figure 4.13):
