"https://www.freelancer.com/users/onlogin.php has a valid certificate as you can see by green lock in address bar."

As you can see, it does not.

"An invalid certificate warning shouldn't prevent you from browsing the site ..."
You're mistaken. Perhaps you are using an older version where you could.

The question from the OP, Einsteins, is "How can I disable the message and navigate to this site?"

More simply, to appeal to others who are having the same issue with twitter.com, how do you ovverride or bypass that like you were able to in the older versions of Opera.

Chrome has a similar issue...but you can fix it by clicking somewhere(not the address bar or any box) in the error window/warning and typing 'danger' without the quotes(STS)

What is the fix for Opera.

Please, no replies that are on a tangent by know-it-alls. Just a reply from someone who might now the answer to the simple question.

Thank you in advance.

I have the same issue. It is not a lock, it is a globe. I am using Opera 23.

When this happens in chrome...I click anywhere in the window and type 'danger' without the quotes. Note: You will not see anything on the screen as you type this. You do not type it in the address bar or anything..just at any randomly clicked part of the screen. (used to have to type proceed...they changed it) at any rate...when I go to twitter.com I get invalid ssl LIKE THE SCREENSHOT THE PREVIOUS POSTER POSTED.

What is the bypass/override on opera. If I want to proceed anyway, let me.

Seriously disappointed with Opera
All browsers suck now. All!
