Checkout page freezing

I am having problems since I switched this site to a woocommerce store site. The checkout page freezes with some sort of Javascript conflict. I can never get past inserting my last name before it freezes up in a matter of seconds. The site is https://imperialguitars.com.

I looked into the general settings. The WP url was set as https and the site url was set as http. Each time I tried changing the WP url to http, the dashboard closed and I would have to log on again. The change would not have been saved. Same thing trying via the database on the server… the change always reverted. I did finally set both urls in the general settings to https, but the checkout page is still freezing.

I have two other store sites running this theme and have never had a problem like this.

Any help would be greatly appreciated.
