I have a site based on joomla 2.5.6, and the zoo (www.yootheme.com/zoo). There are currently Revista YOOtheme templates (www.yootheme.com/demo/joomla/revista).
He wants to replace the templates smartaddons SJ News.
I downloaded the appropriate files: sj_news_template_j17-j25_v1.3, and YT Plugin. After running and the front entrance to the site appeared the message:

Sj Core is missing
You need to install this plugin for resizing images in Content Component and extensions of SmartAddons. Please click here to download the plugin.

After clicking on "click here" smartaddons page appears with the message: Found 0 item
What to download, modify to make it work?

When I run the module from a group of zoo (www.smartaddons.com/joomla/extensions/commercial-extensions/itemlist/cattag?cattag=zoo&catid=17) is on the page where the module is running instead of the content of a message appears:

Fatal error: Call to a member function create() on a non-object in /TMtesty/plugins/system/sjcore/core/sjclass/components/zoo.php on line 64

Hi Łukasz Langner,

Please check the zoo component on your site again.

Do you really install it yet?
