Troubleshooting
Here are the most common reasons why embedding may not work:
- Embed code must be iframe-based (that is, start and end with <iframe> tags). Embed code that uses <script> tags is not supported.
- Only secure web sites can be embedded. Make sure the URL of the web site begins with HTTPS.
- Not all websites allow their pages to be embedded, so you may not be able to embed them, even when they are secure and use iframe-based embed code. If you have problems, check with the website to see if they allow embedding.
- Site collection administrators can control whether users can embed content from external websites. If they don’t let contributors embed content, you may see an error message that says, “Embedding content from this website isn’t allowed.” See your administrator and/or follow the below steps.
