This is an example of a Category List.

In the Global Configuration section under the System drop down menu, there is a list of Components on the left side of the screen.  This is a list of the Components installed on your Joomla 3 site that have global settings that you can control. These settings will be the default, unless you can and have overwritten them on an individual basis.

The pages listed below go into detail on what these settings do for specific commonly used Components.

To set the Global Configuration for all Articles and Categories, click on Options in the set of action buttons at the top of Article Manager. You can also get to these options by going to System -> Global Configurations then selecting Article from the list of Components on the left hand side.

These are the Global Settings for the Articles and Categories but they can be overwritten within the Article, the Category or the Menu Item.  So if you are troubleshooting and it seems like you have the correct setting Globally, but that setting is not showing correctly on your web page, you need to look at the individual settings for that page in the Article, Category or Menu Item itself.

You may be using one of the templates that come included with the Joomla installation, Protostar or Beez3, or you may be using a 3rd Party template. It is likely that you may want to make minor changes to the look or functionality of your template. Since Joomla is an open-source CMS, you can edit any file. You should be careful to edit the files in a cautious and systematic manner.

Also be aware that changes you make could be overwritten when you upgrade your Joomla site, so you need to take the proper steps to assure that you can replace or replicate any customization that you made to your site. 

Following is a list of articles to guide you through the customization process.

There are numerous available extensions for your Joomla 3 website. These extensions add additional functionality that is not provided with the Joomla core installation. 

This section of joom3 will cover how to install extensions, what to watch out for when installing extensions and review some of the most commonly installed extensions.


Plug-In Manager shows a list of all of the Plug-Ins installed with your Joomla 3 Installation. Plug-ins are Joomla Extensions that respond to a trigger, they kick in when something wakes them up.

Many of the Plug-ins that you see in the list will be the ones that are installed with the Joomla initial installation. these are Extensions for things such as the Authentication, Content, Buttons, Search, System controls and User Controls. Some default Plug-ins are disabled.  You may find that you will need to enable them for some 3rd Party Extensions to work correctly or for a specific functionality that you need on your site.

When you click on the name of the Plug-in in the list you will get to a screen with the settings for that Plug-in. some Plug-ins will have all sorts of things you can change, others are very simple. Unless you need to change these settings for some specific purpose, it is best to leave well enough alone.

3rd Party Plug-Ins

When you install 3rd Party Extensions through the Extension Manager, the installation process will often install new Plug-Ins.  In some instances, you need to Enable the Plug-in. The reason that they don't install as already enabled is because they may not be required for basic functionality for the Extension and there is no reason to use system resources unless it is deemed necessary.

You may have heard the term "migrate" or heard the term "upgrade" when referring to changing to a new version for a Joomla website. There is a definite difference between the two terms.

Migration: If you are going from a one release of Joomla to another, say from 1.5 to 3.3.6, this is considered a migration. When you are going from a 2.x version to a 3.x version, this is also a migration.

Upgrade: If you have a 3.3.2 installation and you are changing it to a 3.4.0 version, this is called an upgrade.


Migrations are never a one click update with a few little tweaks. Migrations involve a different database configuration. Some database tables added, some database tables removed. There are other major changes to the way new Joomla sites are constructed compared to older versions.

If the Joomla installation requires a migration, then the template your site is using and any extensions will have to be compatible with the new release of Joomla as well.


Upgrades are usually much simpler. They involve some bug fixes, security patches and the like. The table structure of the database will not likely change with upgrades, any any template or extension currently installed will probably be compatible as well. They recommend that you always keep your Joomla installation upgraded to the latest version for the security of your website.
