If you get the error "Navigation to the webpage was cancelled"
while browsing, chances are a security setting needs to be corrected. In a previous post
I suggested a "scorched earth" settings-reset procedure, but I've found
that that isn't always sufficient. Sometimes the settings need to be
relaxed beyond factory defaults.
instance, our Learning Management System (LMS) uses mixed https and
http content, and Internet Explorer is often set to block mixed content
entirely. Sometimes it will prompt the user but often it will simply
give the error "Navigation to the webpage was cancelled." In the case of
our LMS, a large clue to what is going on is that the login page
appears completely unstyled, because the style sheets and images are
part of the blocked content.
the site to the user's Trusted Sites and setting the Trusted Sites
security settings correctly has proven to be a reliable way to fix the
problem, however I have to make the following disclaimer:
add a site to your trusted sites if you are SURE it is OK. We use this
method because the site is a known site, and protected behind a
firewall. Do not go any further unless you are certain the site is not a malicious site.
OK, you've been warned. If you are sure of the identity and intentions of the site, go ahead:
In Internet Explorer (your web browser), select Tools > Internet Options from the menu at the top.
- The Internet Options window will appear. Select the Security tab.
Then click on the Trusted sites icon.
- Click the Sites button.
- The Trusted sites window will open. Type the URL of the site in the website box as shown. Click Add. Then add an "s" after the http (i.e. make the address look like: "https://trusted.website.com"). Click Add again.
- Be certain that you do NOT check the box for Require server verification (https). Check it twice!
- Click the Close button.
- With Trusted sites still selected, click "Custom Level".
- The Security Settings - Trusted Sites Zone window will open. Scroll down until you see "Display mixed content". Select Enable.
- For advanced users only:
This fix may not be necessary - if you are pretty sure an iframe is
involved and pages that should be opening within the same window are
opening in new windows or not opening at all. Scroll down to Navigate sub-frames across different domains. Click "Prompt." Then click OK to close the window.
- Back on the Internet Options window, click OK to save the changes. Try the site again to see if it works better with these settings.
