In Joomla! 2.5 Essential Training, Jen Kramer uses Joomla! to build a web site from scratch—no programming required—and guides site designers through the process, from installation to launch. The course demonstrates how to create and organize content; add menus, sidebars, and other features; change the look with templates; install plug-ins and extensions; assign specific users to create and edit content; and much more. Jen also shows how to evaluate the quality of third-party extensions and templates and how to download and install them, and emphasizes the importance of backups for your Joomla! site, with details on creating and storing those backups.
Topics include:
- Understanding a content management system (CMS)
- Comparing a CMS-driven site to a static HTML site
- Installing Joomla!
- Organizing content within Joomla!
- Creating categories, articles, and menus
- Installing third-party extensions and templates
- Managing users and their permissions
- Changing the look of the site with templates
- Launching a Joomla! site

Frequently asked questions
Find answers to the most frequently asked questions about Joomla! 2.5 Essential Training.
- Q: How do I add a Twitter feed to my Joomla! site? When following the instructions in the Chapter 8 video "Adding a Twitter feed," I can't access my feed.
- A: The way to access the feed as shown in the video no longer works. However, the ability to generate this feed is still available on the Twitter web site. Rather than following the instructions to navigate to the feed generation page in the video, use this URL instead:
https://twitter.com/about/resources/widgets/widget_profile
Follow the rest of the instructions as indicated in the video, and you should be all set. - Q: I'm having problems embedding a YouTube movie with the Joomla! Content Editor, as shown in the Chapter 6 video "Adding a YouTube video to an article." What should I do?
- A: To correctly embed a YouTube movie in a post, go to Components > JCE Editor > Editor Profiles > Default > Plugin Parameters > Media Support and enable the iFrame option.
- Q: Where can I learn more about how to make a website?
- A: Discover more on this topic by visiting how to make a website on lynda.com.
- Q: After following along with the exercise files, all has gone well until I installed JCE. When I did this my control panel on the backend came up with the following "strict standards" error:
( ! ) Strict standards: Non-static method WFEditor::getInstance() should
not be called statically, assuming $this from incompatible context in
C:\wamp\www\administrator\components\com_jce\models\model.php on line 112
Please advise. I looked for a way of uninstalling JCE and could not find one. The exercise site seems to work quite well otherwise, although I can't change the profile of JCE as instructed because of similar messages throughout the JCE profile. - A: Anytime you receive an error about "strict standards" when work with WAMP (any additional messaging doesn't matter), please apply the following fix. This fix is also described in the Joomla! 3 Essential Training Chapter 11 video, "Turning off WAMP error reporting."
Because the error reporting is an issue with WAMP and not Joomla!, this fix works for Joomla! 1.6, 1.7, 2.5, and 3.0, as well as later versions of Joomla.
1. In WAMP, find the icon in the system tray and click it.
2. Choose PHP - php.ini from the list.
3. Search the php.ini file for the following line:
error_reporting = {there will be some kind of value in this place}
4. Change whatever value is there on that line to the following:
error_reporting = E_ERROR
5. Save and close php.ini, then go back to the WAMP menu and choose "stop
all services", followed by "start all services" to reboot Apache.
6. You should no longer see errors. If errors are still present, then do
the following:
a. follow steps 1 and 2 above
b. Search the php.ini file for the following line:
display_errors = off
Change this to
display_errors = on
c. Follow step 5 above.
