Hi, I'm getting the message - the certificate for server is invalid. You might be connecting to a server that is pretending to be "setup.icloud.com" which could put your confidential information at risk on my IPAD 2. Please help!

Since the HeRtbleed flaw was announced last week, a number of sites have been patching the flaw and then revocting the certificates to prevent fraudulent sites from pretending to be them. They should then issue a new certificate when you login to the legitimate site. Try logging in again.

For your browser, delete your current cache, history and certificates...logging in to sites will take longer until you get new certificates but will clean things up.

Go to Settings > Safari > Clear Cookies to get rid of the old certificates.
