Embedding a content from one website (your content) into another website (Alpana) often requires to be allowed from the embedded website (your content).
This is called Cross-origin resource sharing.
For example, the https://www.google.com/ URL currently refuses to be embedded inside an iframe of another website. This is a normal thing, for security purposes.
In some cases, you can create an exception, please see with the documentation of your content website.
