Web Page Object Linked to Web-Based URL Blank After Publishing

Issue

After publishing a workbook, web page objects in dashboards are blank, or may display an error similar to the following:

This content cannot be displayed in a frame.

Environment

Tableau Server
Tableau Cloud
Web Page Object linked to Web-Based URL

Resolution

Option 1

Remove all web page objects from the dashboard.
Create a URL Action which opens the desired web page. After publishing, this URL action should open a new tab/window in the browser.

Option 2

Keep any web page objects that are behaving as expected, remove the web page objects that are not working.
Create a URL Action to open the URL which was not loading correctly.
In a browser window, add ?:linktarget=_blank to the URL of the dashboard. For example: Server/#/views/workbookname/dashboardname?:linktarget=_blank

Note: If there are any web page objects in the dashboard, URL Actions will open inside the web page object unless the URL parameter "linktarget=_blank" is added to the dashboard’s URL.

Option 3

Remove all web page objects from the dashboard.
Create a new worksheet with any desired view, such as a single mark in the shape of an arrow.
Create a URL Action to open the web page which was not working based on selection of the new worksheet built in step 2.

Note: This option can be combined with Option 2.

Cause

This behavior is caused by the web browser and website security settings. For security reasons, some websites do not allow loading of web pages in an iframe tag.
