jQuery plugin not working on iPhone Safari

[utnalove]

Hello, please check the following two sites:

1
2

What's wrong with site 1? The slider doesn't work on iPhone....

The Safari debugger says:

TypeError: Result of expression '$("#showcase").awShowcase' [undefined] is not a function.

The slider is using the following JS code... the link is in the header: http://glamourina.pl/wp-content/them...aw-showcase.js


Thank you for your help

I just found the root cause, but still looking for help how to resolve it.

The slider is loading a jquery.min.js.
A widget in the footer is also loading a jquery.min.js.

If I remove the widget the slider starts to work fine in iOS devices.
How can I have both slider and widget to work fine together on the same page?
