If this is the usual case, the certificate error is at the specified remote server, and not on your iPhone.


Look for and remove a subscribed calendar you no longer need or do not recognize:

If your iPhone is displaying this message because you are repeatedly visiting Web pages on stanza.co – don't visit them.


If that's not it, look for something else that might be causing your iPhone to try to access the site with the untrusted certificate – such as the "subscribed calendar you no longer need or do not recognize" that MrHoffman mentioned.
