On my site I noticed a day or two ago that my pop up login was not working anymore, and neither was my slide out shopping cart. For example when you click login it is supposed to bring a pop out to the front of the page darken out the main page where you can login and once successful close and refresh the page, it was working great and now it is not. Additionally when you ad something to your cart via the ad button on the main page of a featured product or a sale product, or on the actual product page it is supposed to ad it to your cart and then the cart has a little slide down that come down from the cart button to show you what is in this cart.

I purchased both of these products from Numinix and both were working great for over a month, I started playing around with compressing and minifying my css and jscript and I think I have broken something, everything else works great except you can no longer have the abilities to view your cart or login without being redirected to that specific page, this is not good as some people will loose there place in my site and then have to click all over the place to get back to it or hit the back button on their browser a couple times and refresh, this is a waste of time and my customer like to buy/browse quick without interuption, they are acustomed to these features and now getting confused please help me out I am not sure where to even start debugging in chrome I get this messsage when using the developer tools but I am not sure on how to go about fixing it.

My website is bullysperformance dot com
