Copied off Google, search was 'Paypal error code 70360'
I tried deleting Cookies and turning off Popup Blocker, but this didn’t work.
I added the web address – mbuy.ebay – etc to the – security trusted sites section, but this made it worse, as it constantly wanted me to log back in!!!
The solution I found was to go to the Internet options – Content and select: Clear SSL State (Secured Socket Layer State) and OK.
DESCRIPTION:
If you click Clear SSL State on the Content tab in the Internet Options dialog box, you can remove all client authentication certificates from the Secure Sockets Layer (SSL) cache.
In an SSL session (using https://), when a server asks for a certificate to verify that you are who you say you are, the chosen certificate is saved in a cache. The chosen certificate can remain in the cache until you restart your computer. Clicking the Clear SSL State button removes all certificates from the cache without having to restart your computer.
