Hi Anonymous
The error message warns that an Iframe is sand-boxed without a proper privileges
This is an example of a sand-boxed iFrame.
<iframe sandbox src="http://usercontent.example.net/getusercontent.cgi?id=12193"></iframe>
The sandbox attribute is not always automatically attached, because the sandbox attribute controls what is allowed.
When a pop-up is needed, the attribute will change
<iframe sandbox="allow-same-origin allow-scripts allow-popups allow-forms" src="http://usercontent.example.net/getusercontent.cgi?id=12193"></iframe>The iFrame has to allow pop-ups, new windows, or scripts. Whatever you are trying (probably just navigation), the action is being blocked by a sandbox.
