HTML Pop Up replacing my HTML content

Hi,

I’m trying to create an HTML pop up with the following code,
<div class="fb-page" data-href="https://www.facebook.com/UKinkalla/" data-width="400" data-small-header="false" data-adapt-container-width="true" data-hide-cover="false" data-show-facepile="true"><blockquote cite="https://www.facebook.com/UKinkalla/" class="fb-xfbml-parse-ignore"><a href="https://www.facebook.com/UKinkalla/">UKinkalla</a></blockquote></div>

but once I save it, the page comes up with the following code (not sure why it’s overwriting/deleting part of my html)
<div class="fb-page"><blockquote cite="https://www.facebook.com/UKinkalla/" class="fb-xfbml-parse-ignore"><a href="https://www.facebook.com/UKinkalla/">UKinkalla</a></blockquote></div>

And obviously, the pop up is not showing as it should… Any ideas why?
I’m trying to create a facebook like box pop up with the facebook page plugin https://developers.facebook.com/docs/plugins/page-plugin

Cheers,
Desiree
