I am having a weird issue on my site. (https://clutterbrain.com/)
If I add an item to my cart, view the cart, then click the remove item link I get a 400 error.
Now here is what is really ironic, if instead of clicking the remove item link, I right click it and open it in a new tab the site works file.
Has anyone else ever encountered this? Does anyone have any idea why this is happening?

This is an accepted solution.
If you haven't made any change in code you should just take the fresh copy of theme.js and cart-template.liquid
