Iframe code

Hi @amnwtritaly!

I just tested from my end and I can see that the preview works as expected for the Custom HTML block.

Have you checked if the URL added to the iframe indeed supports iframe? Not all sites would work as expected, but you can use the following for testing:

<iframe src="https://example.com/" title="Iframe Example"></iframe>

PS: I see you’re actually using the HTML block on the Block Editor (not the Classic Editor plugin), so please create a topic on the general forums if you still need help with it. Feel free to add this topic link as a reference.

The code you provided is working in both cases (block and classic editor).

<iframe sandbox="allow-popups allow-scripts allow-modals allow-forms allow-same-origin" style="width:120px;height:240px;" marginwidth="0" marginheight="0" scrolling="no" frameborder="0" src="https://rcm-eu.amazon-adsystem.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=lightnovelexpert-21&language=it_IT&o=29&p=8&l=as4&m=amazon&f=ifr&ref=as_ss_li_til&asins=8834911318&linkId=fe5ae8c557edae1f206362bb456e3e37"></iframe>

This kind of code is not supported, maybe?

Resolved.

It was the AdBlock.

Thank you.
