I was about to install a YooTheme tempalate on one of my slave sites when I remembers seeing this on here.

What are these patch definitions for exactly? I'm just using a Yootheme template on one site, do I really need this?

Yoothemes have bugs in their WARP framework.

This is something reported several times to Yoothemes and as they still not fixed it, we have developed a specific plugin to fix some bugs for some templates and some extensions.
If you are using YooThemes, we suggest that you ask Yoothemes to fix their bugs.

If you want to buy our extension, verify the version of Joomla and also if the themes or extension is present for your specific case.

The patch is specific for a specific joomla version, specific warp version and specific yoothemes extension or themes.
