<![CDATA[Invalid Server Certificate]]>I try to load twitter.com and "invalid server certificate" screen appears. What can I do? What can I do when this screen appears when I try to access other sites too?
Sharing directly on twitter with a sharing extension, requires my log in, which seems impossible.

That explains it.

I'm getting error popups here on this forum in Opera 12.17 -
"invalid server name" on files.opera.com

The error popups about files.myopera.com occures because someone had inserted some picture in a posting from a old Opera domain myopera.com, which does not exist anymore.

Running XP with latest service packs. Read the same recommendations about computer time/date, Antivirus SSL, both of which did not solve the problem.

As of yet there is no working solution for this issue.

Our company has been instructed to not use Opera. I wish this issue would be resolved but thus far I dont see any actual solutions just a few ideas that dont work.

Check the date on your computer. Browser certificates have a start date and an end date. If your computer date is set to far of one way or the other, that can cause this problem.

I'm running Opera 22.0.1471.70. I googled this and found that the problem is for a "Chrome client" running on Windows XP SP2. The recommended solution is to upgrade to SP3. Twitter is using a certificate that is not supported on SP2.

As Twitter is working with Opera 12.17.1863 and SP2, is it possible to remove the troublesome certificate in Opera 22?

It is not a lock, it is a globe. I am using Opera 23.

It just means that the site is not secure.

Can you click on the globe and then in "details" and post here what it says? If possible, post a screenshot.

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!

At the same time? Could you please take a screen shot?

It shows nothing, if I click on it. Before click, it is "twitter.com", the site I try to reach. BTW, even a screenshot with an extention is not possible. I did it classically with Fn + Print 🙂

Strange. It shows the padlock or just the globe icon?

Dont let the Antivirus or Desktop Firewall scan your SSL connections, these "safety" programs crack SSL by using own certificates giving invalid certificate warnings on browsers.

@angiesdom How can I do that? The AV is not actually "working" since it's disabled, at least when I use Opera. >>> I use Opera 22, the last "normal" version. I have Avast AV, but it's disabled. How can I post the screenshot? Or, where? I'll look at avast if it's blocking anything, or at the Windows firewall. I'm unfortunately on XP Professional.

And here is the screenshot:

If you click on the badge/padlock at the address bar and then on "details", what does it shows?

You can upload your screen shot to an image hosting site, such as http://tinypic.com/ and post a link to it here in one of your posts.
*Other image hosting sites exist too. It's just that tinypic is the simplest I have found, and you don't even need to create an account to use it.
