QUESTION Iridium Mobile Menus not showing

[orders]

I am new to GetSimple, and found Iridium as a great theme to use. However I cannot seem to get the mobile menu's to appear in/on any mobile device or test. Is there anything specific I should be looking at?

Modifications -
I did disable the featured area due to the client's lack of information. Just used <!-- tag in template.php.
I did change the banner.jpg
Modified the size of the logo text smaller

Please advise if you any direction on this one.

Thanks!
