How to Install Joomla 1.5 Templates
The installation of Joomla 1.5 templates is easy and requires just few steps from you. First, you need to have the archive of the template stored somewhere on your hard drive.
To start the installation, access the admin panel of your Joomla 1.5 site and go to Extensions -> Install/Uninstall in order to open the Joomla Extensions Manager.
Next, hit the Browse button and locate the template archive on your computer. Once you find it, click on the Upload File & Install button to proceed.
Once the template is installed on your website, you need to make it default. To do this, go to Extensions -> Template Manager. From this page you can manage the installed templates on your Joomla 1.5 application.
Now, select the newly installed template and lick on the Default button (yellow star at the top-right corner of the page).
You are now ready! You can go to your site and check out its new looks!
PS. If you have the default or 3rd party caching enabled you may have to clear your cache in order to notice the changes!
