Cart button wasn’t working properly

After I installed this plugin, my cart button wasn’t working properly. I am using Mr Tailor theme, and when I press on cart button, right panel should slide out and there should be my added items or “No items added” text. But after this plugin, this panel was blank, no text, nothing, it was only working on product page and shop page, on other pages didn’t. So after I switched this plugin off, it’s working properly again. It might be a problem of theme too, but it wasn’t good for me how it was with this plugin.
