In the product page, my top menu (RokNavMenu) is not appear properly
1- Yes, inoticed that the main menu doesn't work okay in the product details page. I will investigate it. Looks like an easy patch but can't say anything without looking into backend.
The links on the images and icons are not working always (add to cart, larger view, etc...)
2- This caused by your social media module on the left edge. If you look at the screenshot, you would understand:

I don't know why it is so long and goes all the way to right. This is why "sometimes"links don't work. Because the module's DIV element overlap the website and everything will stay under it. You should better find a better social media plugin or complete disable that, using float plugins at the edges usually gives nothing but problems or leads a jQuery Conflict issues.
In the pop up of the "quick look" , the links are no working
3- Same thing happens in QuickLook as well. It is all that media module's fault.
we can't choose a selection in the sorting select in category view
4- Same thing happens in QuickLook as well. It is all that media module's fault. If you scroll down little bit and get away from media module, you will be able to choose sorting.
5- I noticed some minor issues that caused by CSS overriding caused by your joomla template.
To solve 2,3 and 4th problems, you should unpublished that module and everything will be good to go.
