I keep getting this error when trying to get into an online account I've used for some time, is trusted and a secure site. I can no longer access it but receive this error. I'll admit I don't even know what it means, it's just making life difficult.
I am absolutely not technical but can follow guidance of someone who is and who can help me. Thanks!

Try going to Applications/Utilities/Keychain Access and see if you can delete the site's certificate. That should cause a new on to download. Quit and reopen Safari to test.
