Unrecognized iframe rendering in Wordpress markup - wordpress

I was inspecting browser elements on a Wordpress 3.4.1 site and came across an iframe I don't recognize.
<body class=" customize-support">
<iframe src="http://mickajoin.tumblr.com/?d=www.example.net" frameborder="0" marginwidth="0px" marginheight="0px" scrolling="no" width="0px" height="0px"></iframe>
<div id="wrapper">
...
Of course http://mickajoin.tumblr.com doesn't exist so this returns 404 anyway. Searching the project resulted in nothing. Google returned nothing relevant.
Initially I thought it was the Gallery plugin. I disabled it and the iframe persisted. I've also deactivated the other 2 third-party plugins use on the site. None of this worked.
I'm hoping someone can point to me the sources of where this could be injected.

Thanks for the tip on the extension. Turns out it was Pokemon Tower Defense HD 5.6 for me. ^_^

Youtube iframe fullscreen

hope everyone is ok.
I need to build a page in our company's website where we're putting some videos of our production.
The problem is, i can't seem to find a way to make the videos available in fullscreen mode for the visitors.
I've done pratically every solution that i've found, but none seems to work. I've done:
<iframe allow="fullscreen;">
---
<iframe src="your_page_url"
allowfullscreen="allowfullscreen"
mozallowfullscreen="mozallowfullscreen"
msallowfullscreen="msallowfullscreen"
oallowfullscreen="oallowfullscreen"
webkitallowfullscreen="webkitallowfullscreen">
</iframe>
---
allowFullScreen="allowFullScreen" and frameBorder="0"
---
<iframe
id="player"
src="URL here"
allowfullscreen="true">
</iframe>
---
But none of that worked.. Any help here is welcome!
its very easy if you wants to add youtube videos in iframe .you just have to add iframe in src embed word like that
<iframe src="https://www.youtube.com/embed/watch?v=fbS2O4VETAo&t=2s" name="myFrame"></iframe>
after youtube.com/embed/Example url

How do I fix a 404 Error created through data:image/gif;base64 being added to my site?

I have been trying to figure out why each image on my WordPress site is resulting in the following code being changed in all images I upload:
<figure class="wp-block-image size-large image-shadow img"><a href="https://www.example.com/blog-post-title/" target="_blank" rel="noopener noreferrer"><img width="600" height="400" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://www.example.com/wp-content/uploads/2020/08/blog-post-title-image-1.jpg" alt="image description" class="wp-image-18844 lazyload" data-srcset="https://i1.wp.com/www.example.com/wp-content/uploads/2020/08/blog-post-title-image-1.jpg?w=600&ssl=1 600w, https://i1.wp.com/www.example.com/wp-content/uploads/2020/08/blog-post-title-image-1.jpg?resize=300%2C200&ssl=1 300w" sizes="(max-width: 600px) 100vw, 600px" /><noscript>
This results in Ahrefs scans displaying 404 errors for all URLs; for example, the URL below loads fine, but there is an added /images/gif to the string.
https://www.example.com/blog-post-title/
becomes
https://www.example.com/blog-post-title/images/gif
in the Ahrefs report coming from the crawl. It seems from what I have been able to find out that the issue may be coming from here:
src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"
I host on SiteGround and use their CloudFlare addon with some settings applied through my CloudFlare account.
Has anyone else encountered these 404 errors? If so, may I ask how they were resolved?
I've experimented with various redirects to the post (which haven't worked and maybe the completely wrong thing to do).
It seems that this issue was triggered by the JetPack Lazy Load settings. These have since been turned off and the issue has been resolved.

Lazy sizes does not show video

I am using lazy sizes for the lazy load of my youtube videos. On every page the lazy load does work, but not on these two, more precisely, the whole video just disappears/is not displayed. The two pages are in the same folder as all other pages, which do work. The link to lazysizes.js is there <script src="lazysizes.min.js" async></script>
Here is the iframe on one of the working pages with the video being displayed:
<iframe width="640" height="360" data-src="https://www.youtube.com/embed/xxx?rel=0" importance="low" loading="lazy" frameborder="0" class="lazyload" allow="encrypted-media" allowfullscreen></iframe>
and here the iframe that just won't work/does not display the video - it's identical:
<iframe width="640" height="360" data-src="https://www.youtube.com/embed/3FOZ2CTaaWk?rel=0" importance="low" loading="lazy" class="lazyload" frameborder="0" allow="encrypted-media" allowfullscreen></iframe>
I know this just doesn't make sense, but my hope is that one of you stumbled upon the same problem. I have tried copying and pasting (swapped them, so it is not really the iframe code) and changing it, reloading the js etc. but nothing helps. The iframe is identical with the other pages. I have no idea how to find out what's missing here.
I'm stupid, the console revealed it: the lazysizes.min.js was loaded into the directory of this particular URL. Since this URL (and its /.../ directory) is artificially created the lazysizes.min.js could not be found in that directory (though on the FTP server the js file is in the same directory as the source php file that loads it) it could not be loaded.
A simple line of extra code that includes the lazysizes.min.js above the iframe embedment with an absolute URL to the js file solved the problem!

YouTube Iframe Tags no longer display CC

It appears that an update adding widget_referrer was added to the YouTube API on June 12. The CC no longer shows up for my videos and the language in the settings no longer shows up. It works on YouTube correctly, but not in my iframe tag shown (mostly) below.
iframe frameborder="0" width="640" height="360" src="{{ video.url }}" /iframe
(It's django - the video.url reference works fine.)
I've monkeyed with cc_load_policy, origin, and putting something into the widget_referrer with no success. Any suggestions would be greatly appreciated (for example, I just put http:\mydomain.com as the widge_referrer. Should that have www. in it?)
This problem no longer exists. I assume that it was a bug and someone fixed it at YouTube. --thanks--

TinyMCE Stripped the allowfullscreen attribute In iframe?

Hi have gone through documentation of TinyMCE but could not able to find why TinyMCE Stripped the allowfullscreen attribute In iframe ? When I insert and re-edit it stripped .
Tried iframe URL
<iframe src="http://players.brightcove.net/4338955589001/Bkh63tBcx_default/index.html?videoId=5347595845001" width="320" height="240" allowfullscreen></iframe>
Live Fiddle code. Thanks for help
You can use the valid_elements attribute to tell TinyMCE what valid elements and attributes are allowed in the editor.
I updated your fiddle: http://fiddle.tinymce.com/8Lfaab/1 with the following configuration line:
valid_elements: "*[*]"
Admittedly you likely don't want to include all tags and all attributes but this shows that you can get this working.
Please note that your Fiddle is using TinyMCE 3.5.x - that version of TinyMCE is no longer under development. It would be a really good idea to move to TinyMCE 4.5 which is the current release and under active development. If you use TinyMCE 4.5 you can use extended_valid_elements as opposed to valid_elements.
