Can't get into website because it says security certificate expired even though it is dated April 21, 2021. One tip said to delete the expired certificate and log onto the website and it would renew. This didn't happen.
Security Certificate expired to a website often used. The certificate indicated expiration was April 21, 2021. Safari would not let me in. One tip was to delete the certificate and log on to the website and it would update. This did not happen and now the certificate is gone. I am at a loss to fix this. None of the information I've found works. There is no indication anywhere on how to update the certificate of fix this issue.
