The Zen grid Framework version 3 plugin is a Joomla 3 update for the Zen Grid Framework plugin. This document describes the process involved for updating a template built using Zen Grid Framework version 2 (ZGF v2) to Zen Grid Framework v3 (ZGF v3).
The following instructions are designed for users who want to move an existing Zen Grid Framework theme to Joomla 3 using the Zen Grid Gridge version of the same theme. The following steps are only necessary if you have made physical changes to the files. If you have only made adjustments to the template via the template settings then this is not required as a part of your migration to Joomla 3.
1. Download the ZGF v3 theme from your selected theme's download page.
2. Extract it on to your desktop.
3. Download your current theme (ZGF v2 theme) to a new folder on your desktop.
4. If you have made changes to any css files - copy the entire contents of the css folder from your original theme to the css folder in the bridging theme. It's ok to overwrite the bridging theme's files with your own files.
5. If you have made changes to any image files - Copy the contents of the template image folder from your original theme into the bridging theme image folder.
6. If you have added any javascript to the template append it to the js/template.js file - before the closing bracket. Otherwise leave this file as is.
7. Then re-zip the ZGB theme files so that your css and image files are in the new zip.
8. Install the newly zipped file via the Joomla installer in Joomla 3 only.
9. Install the Zen Grid Framework v3 package.
10. Go to the template administrator and edit the template parameters to reapply your desired layout, appearance and other settings.
11. Save your changes and set the template to default.
12. Go to the plugin manager and ensure that the T3 and ZGFv2 plugins are disabled if you have them installed.
13. Go to the front end of the site to check the layout and appearance of the themes.
Please note that if you have made any layout overrides for your theme you will need to check the changes against the new version of the template. Zen Grid Framework v3 themes implement new markup and php functions so it is not possible to simply drag and drop the files located in the layouts folder.
