By trying to add the My Content Embed link to SharePoint some users will see an error message that says, “Embedding content from this website isn't allowed.”
If you want to embed content from external websites (e.g. The Valotalive My Content Embed Channel) on Sharepoint pages you first might need to permit embedding iFrames in SharePoint.
The steps to follow are:
Browse to the root site of your SharePoint site collection.
Click Settings, click Site Settings. If you don't see Site settings, click Site information and then click View all site settings.
On the Site settings page, under Site Collection Administration, click HTML Field Security.
Chose Allow contributors to insert iframes only from the following domains.
The domain in question to be added as trusted domain in SharePoint security settings is store.valotalive.com
NOTE ! If you don't know how to setup the iframe code, please contact us for further support.
