Проблема! Обновление Zoo с 2,2 до 2,4 - ZOO 2.х

Now follow these steps to update your ZOO 2:

    1. First of all make a backup of your old site (files and database), so you can recover it any time.
    2. Download the latest ZOO version (one of the distributions from above).
    3. Go to the extensions installer in the Joomla! administration, pick the downloaded ZOO package and click on Upload File & Install.

That's it! Now the ZOO extension, all language files and all bundled modules and plugins are updated to the latest version...
Depending on your installed ZOO 2 distribution the apps, plugins, modules and tools are also updated when updating ZOO. So any modifications to the files (PHP, CSS, Images, etc) may be lost. Therefore we recommend to duplicate an existing app (and rename it) rather than editing the original app. So if you don't use the original apps your custom app will still be untouched during the update process.

When you've finished the update, clear your browser cache and the Joomla cache. To clear the Joomla cache go to the Joomla administration - Tools - Clean Cache.
