I realized that I wrote about how to uninstall atemplate, how to delete a template, how to activate a 1.6 template but I didn’t write about how to install a 1.6 template. To install a 1.6 template is pretty easy, I just overlooked it because some Joomla 1.6 templates now are all quick installs.
When you download your Joomla 1.6 template it is in zipped format. I would unzip the file because sometimes the developer buries all the template files down in subdirectories. Go to the subfolder that contains all the template information. Your subfolder should contain for example index.php, config, plugins,, modules, and admin folders. Zip that subfolder up and name it for example template123.zip.
Below are instructions how to install this template to your Joomla 1.6 website.
1. Login to your Joomla 1.6 administrator backend.
2. Click on,
3. Click on the Package File box and select the template123.zip file. Click on ‘Upload and Install’ button.
Hope that helps,
