https://secure.img-cdn.mediaplex.com Keeps Popping Up

I have been getting it the last few days on a site that I visit regularly. I am using Chrome as my browser.

It may have something to do with AdBlock. Do you have that installed?

Hi, did you have any luck with this? I have this thing popping up on my computer now too 😟.

Rob, I am still getting it. Do you have any sort of ad pop-up software installed?

It is a pain because I have to click on the OKAY button for the page to finish loading.

Im having the same issue since i did the OS X update 4 days ago . PLEASE help .😕

I have the same issue but on Windows 10 and Firefox 40.0.3 and 41.0. The only temporary fix I've found is to run SuperAntiSpyware (free version works) and allow it to delete all cookies. I also ran MalwareBytes to make sure it's not malware. This seems to work for about a day or so and then I get the stupid pop-up again. Someone needs to look into this.

Seems it is being caused by Google.

You can try installing the Google DoubleClick opt out plug-in.

This is the one for Chrome. You would have to see if there are similar ones for other browsers.

Yup me too...it's driving me crazy. It only happens when I am watching a Youtube clip

Seems it is a glitch with Google.

Since I am tired of Google tracking my every move on the Web and then targeting me with ads that they believe are best for me, I am not using them as my default search engine anymore.

Now trying DuckDuckGo and not getting the problem anymore.

From what I'm hearing about this online, it sounds like it may be a temporary problem with some of the ads being served up on Google-owned pages (such as YouTube). Is anyone having the problem on a page that is not owned by Google?

Edit: Also, can someone having the problem upload a screenshot of the problem?

This error pops up whenever I go to youtube or a few other sites that use ads from mediaplex. The ad fails to load and generates this error.

I do not use any ad blocking type software.

That looks like it's probably due to an error in the JavaScript being loaded by one of the ads.

I cannot duplicate this here, using the same site and same search criteria, even after reloading numerous times (to get different ads) and making sure to load the Flash content in any Flash-based ads. This means it may be a regional thing, or related to an ad that is being specifically targeted to you and not to me, or it may be fixed now.

If it's continuing to happen, I'd recommend choosing Clear History and Website Data from the Safari menu. If that doesn't solve it for you, an ad blocker might be called for. AdBlock is a popular one.

I think you're right. I realize these are Apple Forums (I have a MBA as well but my issue is on a WIn PC using FF 40.0.3 or 41.0). Since the URL includes "cdn", perhaps this is geography-specific, i.e. Canadian IP addresses only? I could try using a proxy to see if it still occurs, to narrow down the issue, since you are not seeing the problem.

I use a Firefox add-on called Strict Pop-Up Blocker on Win 7 and it does not prevent the mediaplex msg from appearing. A temporary fix is to delete all mediaplex.com cookies, as well as run a scan in SuperAntiSpyware (freeware), then it seems good until, like others, I go to YouTube and voila! it rears its ugly head again.

I guess the issue is to find out who the culprit is and contact their tech support for a fix.

Clearing History & Website Data only provided a temporary fix. I have AdBlock and that did not prevent it.

The problem was caused by Google. Since changing to DuckDuckGo as my search engine, I have not had the problem.

Actually, "cdn" in this case means "content delivery network." It's a common abbreviation used to refer to servers whose sole purpose is the high-volume distribution of something like advertising, software downloads, etc.

My bad. Thanks for clarifying and correcting, I learned something new as a result. 😉
