I just added a page viewer web part to my site page and entered the link to the URL I want displayed. Now, every time I go to that site page this message pops up on the bottom of my web browser enter image description here

The page viewer web part won't display until I click on "Show all content". If you don't click on it fast enough, the message disappears and you have to refresh the page to see it again.

    that is expected if you are linking to http content on a https site like sharepoint online Aug 10, 2015 at 14:54

  • Internet Options -> Security tab -> trusted sites. Bellow you will see a button "Sites", click on it and add the url of your site in the displayed window

Your site is most likely accessed via HTTPS:// , correct? If so, all links that display content on your site also need to be HTTPS.

So, if you site is: https://example.com ...and you attempt to load content from a different site (using a page viewer web part in your case) it ALSO needs to have the HTTPS:// protocol. So instead of this:


do this:


..to access your external content.

  • Correct. It is https://. I will give this a try.
