It just didn’t work

Hi @lmoraless

Can you post the shortcode you used?
And can you share the URL with the issue?

This is your shortcode:
[iframe src=”https://www.youtube.com/embed/oDlbBy9vfgI” width=”100%” height=”500″]

This is my shortcode with my own url:
[iframe src=”https://hotels.cloudbeds.com/reservation/lDoVFZ” width=”100%” height=”500″]

It has been added to a page named Iframe in the text view of the editor.

This is the url, as you see a blank page is shown:https://www.imiloainstitute.com/iframe-imiloa/

This is the iframe code I can see in the DOM:
<iframe src width="”100%”" height="”500″" scrolling="yes" class="iframe-class" frameborder="0"></iframe>
As you can see something is messed up with the quotes and WordPress cannot parse it properly.

I tried your shortcode and it worked fine for me.
Try to re-type the quotes around SRC param. The quotes can be sometimes messed up by WordPress content editor.
Or if you are using the Gutenberg editor by default – you may try to insert your shortcode into the shortcode block. It should not messed up the quotes.

Here is the video where you can find the shortcode block in the Gutenberg editor:

I am using another plugin that is working fine, thanks anyways!
