how to remove 'stags.bluekai.com' pop up

Hi

I am having the same issues, which started yesterday, firstly on mac rumours, then ebay and this morning John Lewis website. I am currently running Mavericks 10.9.5 and can't upgrade my OS as I also have the issue of software and hardware no longer working. I saw on one forum about installing Avast antivirus software, but some say this will affect the system, so I didn't proceed. When I check in safari preferences privacy, there is no cookies for either stags or bluekai, so no option to remove them. When I get the drop down security certificate, I click cancel, which is possibly why it doesn't appear, but am not sure if this affects the running of the sites.

I see that another user suggests empty caches (not sure how) and you suggest installing Disconnect. Will Disconnect affect the running of the machine, as in antivirus software? Have tried John Lewis site on firefox and seems to be OK, so much be a safari issue.

Any help gratefully received as am starting to get fed up with constant drop down window. Thanks

Well I have settled this issue for myself after hours of agony this will become more of the norm from apple support that there is none they have no passion to resolve this issue.

What will work is to in the Safari settings Preferences, set cookies and website data tracking to Never.

And as you come across websites that you use that will not respond as usual move them to Firefox and this will end the drop down issue.

The majority of your bookmarks and visited site's will be just fine with Safari and you will have stopped the issue.

I can only guess this problem is going to grow but having to split your viewing between the two platforms will get you

thru it, and Firefox is showing not to be buggy with 98% of site's visited.

Hope this will be the fix that will work for all......

I've installed Disconnect which has cured the problem for me. There have been one or two issues in Safari, but emptying caches or quit / relaunch resolves them, and they may not be related to Disconnect anyway.

This is not your problem.

It is caused by poor attention to detail on an advertiser site. You do not have any issues on your computer, and there is nothing you can change that will eliminate the message. The problem is in the web ads from this incredibly sloppy web-advertiser.

The extension "Disconnect" is the only thing that has worked for me. It does have the side-effect of blocking other more benign pages from loading but you just need to turn it off but remember reload it afterwards.

Good luck!

Unfortunately, many other sites have begun to have certificate authentication issues as well, so it isn't just a problem with the stags.bluekai.com certificate. It is an issue with Safari on Mac OS 10.9. I have also noticed that suddenly many sites that I visit on a daily basis have stopped functioning properly with Safari, but work fine on Firefox. These ones in particular all worked fine on Safari up until about a month ago.

Yes, I've noticed this too. My question is - why should so many different sites have certificate issues with Safari 9 in OS X 10.9? I'm thinking this must be an Apple issue, not external, or it wouldn't have suddenly have started to happen with so many different websites.

If already running the latest Safari for 10.9.5, then unless you are willing to move to a later version of MacOS, or Bluekai comes to their senses and fixes their certificate issues, you will continue to endure that error message.

It is not a pop-up, it is a legitimate error message generated by your computer in response to obvious faults in certificates in the bluekai advertising networks.

I'm afraid that would be true if it was only bluekai that was at fault, but several certificates have become not recognised / invalid - all starting all of a sudden in the past few weeks, and only in Safari. Therefore it's an Apple problem.

I tried all the same advice offered elsewhere. I cannot update my OS due to other dependent software. The only thing that worked for me was to install the Disconnect privacy tracker. I signed up for their basic service which asks for a one-time donation.

I now have this pesky, buggy issue too. It definitely seems to have started after I went to ebay, although I suppose it could have happened at any website. I first saw it when trying to navigate to ESPN.com yesterday. As soon as ESPN loaded, the popup certificate warning came up: "Safari can't verify the identity of the website tags.bluekai.com. The certificate for this website is invalid. You might be connecting to a website that is pretending to be tags.bluekai.com, which could put your confidential information at risk. Would you like to connect to the website anyway?" Crazy. I'm at Espn.com not bluekai. So it wants to redirect...I guess? Not sure because I simply leave ESPN when it happens.

I spent the better part of yesterday attempting to fix this. Read a lot. I'm unable to find a working solution aside from "use Firefox." True. It doesn't happen on Firefox but Firefox upgrades their browser and Apple no longer updates Safari for older systems. I prefer Safari as my default browser and I find it hard to comprehend -- no one has figured out a fix.

Yes, I have tried everything suggested on the Apple forums and other trustworthy sites. Nothing has succeeded in making this 'bluekai certificate warning' go away.

What I am also seeing is this issue had a lot of traction in early-mid February 2018. After late February, I don't see additional reports or complaints. That leads me to thinking there IS a solution and I have not located it.

I also noticed if I disable Java from Safari, the tags.bluekai.com certificate popup disappears. (Is this thing even considered a "popup?) However, once I disable Java, I cannot see the content at Espn.com so certainly not a fix but makes me wonder about Java issues. Why is any site still using Java? Rhetorical question.

Machine specs: MBP 17" 2011

1TB SSD/2.8GHz Intel Core i7/8 GB RAM

OSX 10.9.5/Safari v.9.1.3

Other: No virus or adblocking software installed on machine

** I don't want to turn this into an off topic discussion about those of us who LOVE our 17" MBPs and why we are unwilling to upgrade to High Sierra. Suffice it to say, as long as I can keep this machine going, I need it for work purposes. I don't want to install High Sierra unless/until Apple makes another 17" laptop...which I realize probably won't happen. There are a lot of us who are hoarding and protecting these "vintage" machines because there are no alternatives on the market. Just trying to explain why the simple solution of "upgrading the OS" isn't viable to a certain population of Mac users. Truly don't want/need to get into an off topic discussion of pros/cons of newer machines.

I also ran the Etre check. Didn't want to create an even longer post if there is a simple fix I am not seeing. I'd happily post the results if anyone thinks that would be helpful. Or -- if there is anything else I can tell you about the computer or pesky bluekai issue, ask away and I'll answer. I'm certainly no programmer but do know my way around Macs. I've been using them for 25+ years.

Thanks, all. Appreciate any help or suggestions, in advance.

Nope, didn't help at all. Any other guesses?

I have the same thing... started last week!

Thanks.

Thank you for your post. Very insightful.
