JQuery UI conflicting with another plugin

I am having trouble with a plugin called Savvior ( https://github.com/attila/savvior ) - the plugin seems to be conflicting with JQuery UI elements like the datepicker, accordions and tabs...

Please refer to this post here https://github.com/attila/savvior/issues/15#issuecomment-100176655 for detailed information as well as the plugin developer's suggestions.

I have tried the developer suggestion and it seems to worked, but not on Firefox.

Here is a live test: http://loai.directory/test and this one has what the developer suggested applied: http://loai.directory/test/test

I need someone who is experienced enough to help me sort this out.

Thank you,
Leo
