I found that when I went to the PayPal home page to log in, the page came up in French instead of English. I call PP support and she told me to go to the bottom of the home page and see what flag was showing in a small image. I then saw that it was the French flag. She had me click on the flag and then select the U.S. flag. This has seemed to fix the problem. Hope it keeps working.
