Open the blocked website (Facebook and twitter are popular suspects) in another browser e.g. Firefox. Once open, just next to the URL you will identify a tiny green lock. Click on it. On the emerging window, click on the “more information” button.
You should land into yet another window. Here, also click on the Security tab situated at the right hand side. Now click on “show certificate”. Switch to the details tab.
You will be shown the current certificate for the website you opened. The syntax should be something like this: “VeriSign Class 3 Public Primary Certification Authority – G5 certificate”
Next, open the keychain. You can do this by clicking CMD + Space Bar; then input “Keychain”. OR go to Utilities and access Keychain from there.
Then click on system roots for all entries. You will find here your certificate and it will have a blue cross marked on it. Double click it and another window will come up. You have the option of choosing system setting, always approve or always reject.
You will realize that the certificate was the problem all along. Usually, a certificate will be locked on to the mail server and it will prevent any other website from using it. (Your mail server should be the entry starting with the “smtp” prefix and ending with a “.dk” suffix. Why the certificate would be locked to the mail server is as good as anyone’s guess.
Change the authentication of the certificate to “System setting”
There you go! All the pages you need will be loaded flawlessly on Safari.
