Help! As of a couple of weeks ago, I began receiving the error code "Expired Security Certificate" in Yahoo! mail when trying to Compose a new email. I was able to send email from my Gmail account, and have had to rely on that. Now, I cannot even send from Gmail - it causes Safair to crash. I continue to get the Security warning on Yahoo! I searched online for fixes, including looking in Utilities and the key folder. I see the problem keys, but "repair" does not fix them. The Yahoo! one is dated "Saturday, April 15, 2013" which is obviously incorrect, as today, is Monday, April 15, 2013.
My Safari is also beginning to randomly crash. I just ran updates, but it didn't see to help.
