For the past several days, I am unable to sign out meaning that I am signed in constantly

Yes. It's eBay's way of allowing scammers to take control of your life while you sleep.

Read one of the many other threads on this topic.

Same here - keep getting a 'Can't find the page' message

Have deleted my browsing history for the last month and still can't sign out

Did you do the full clear (including cookies and cached) and then re-fresh the same page (that works for me using Edge as a browser)

Or trying going to the .com site and logging out there as has been suggested by other people who that has worked for?

Or seen if you can contact eBay (some people can,some people can't)
