I don't use IE but a quick Google search took me to a page which says that IE11 disables cookies by default, which isn't very helpful of it. Try this to see if it works:
Click on the Tools icon (gearbox) and select Internet Options
Click on Privacy, then on Advanced
Click on box labeled Override Automatic Cookie Handlie
Under First Party cookies, click on Accept
Under Third Party cookies click on either Block or Prompt. (If you choose Prompt, you may get asked to accept cookies from sites you didn't realise you were linked to; if nothing else it's a lesson in how linked various sites are, through advertising, data collection, etc.)
In the box labeled "Always accept session cookies" I would select that as those cookies are what makes shopping baskets work, and sometimes membership sites use them too - this type of cookie is always deleted when you close the tab/browser.)
Then click OK to exit popups.
You may find your layout is different according to which operating system you use but the basic steps should be more or less the same. It might be useful to empty your cache and reboot before going through the above process. Let us know if it works - or not.
The Hubble Telescope has just picked up a sound from a fraction of a second before the Big Bang. The sound was "Uh oh".
