I have built a site for a client using Woocommerce and Wordpress. The site is working on chrome, firefox etc. but the payment system seems to lag and cancel orders on Internet Explorer. When logging in the loading icon just seems to continuously spin with nothing loading.
You may want to try deleting your browser's cookies, cache, history, temp files, etc. Sometimes when testing button code and/or web sites, previous stored cookies and temp files can cause unexpected results - always best to get a clean start when testing. After you delete your browser's cookies, etc., close the browser, reopen it and retry your site.
