Video posts issue (404)

Hi there,

On this page we have an overview of all our blogposts in Video format:

As you can see we have an issue with the display of the videos. Somehow a 404 is appearing in each video preview:

Please advise what to do because the embed codes are fine, videos still exist on YouTube and tbh the videos have worked fine for years.

Thank you in advance.

Best regards,


Hello Nick,

Thanks for writing in!

Please try out following solutions and let us know the outcome:

  1. I see that you are using WP Rocket plugin, please try clearing the cache and see how it goes.
  2. Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

If you still have problems kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.

Thank you.

Hi Prasant,

Thanks for your reply! I tried both step 1 and 2 but unfortunately no success in fixing the issue.

Please find attached the credentials to our dashboard. Thank you for checking.

Hey @slimenvoordelig,

We’re sorry for the confusion. This is a known issue in the X 6.5.6 which will be fixed in the next release. If you have lots of videos, I’d recommend you revert to a previous version of your site. Alternatively, you can change the double-quotes (") in the embed code to single-quotes (').
