Use MageBridge with Advanced Module Manager - Yireo

This is most likely due to the fact that MooTools has been disabled on the page, but some other MooTools-based extension still has a requirement for MooTools-framework. Because MageBridge loads Magento in your Joomla! environment, and Magento uses the ProtoType-framework which conflicts with MooTools, MageBridge needs to disable MooTools.

You can use the MageBridge configuration to disable all Joomla! scripts (except jQuery and Prototype based scripts), or you can customize which scripts needed to be disabled.
