If you are on a windows machine, search for delete browsing history in the search bar at the bottom. It opens an Internet Properties dialog box. The General tab should be open. At the top of it is a Browsing history section. Click the Delete... button. A new window opens. I left "Cookies" alone, but I cleared Form data, and that did it.
If that doesn't work, maybe try deleting the temporary files as well, but I thought form data was it. (I'm trying to remember!).
