While testing my Bootstrap 3 website, I noticed that the hamburger menu was functioning correctly with the local file. However, once I hosted the site on GitHub Pages, the navbar stopped working

I recently created a test site using Bootstrap 3 (). Strangely, the hamburger menu doesn't seem to be working on this site. However, when I open the local file, the hamburger menu functions properly. Can anyone provide any insights or solutions regarding this specific issue?

Answer №1

It appears that the issue at hand is related to jQuery, which is causing a blocked loading mixed active content error. https://i.sstatic.net/KtWm3.png

I found this solution for the problem on the following question:Why am I suddenly getting a "Blocked loading mixed active content" issue in Firefox?

But what exactly is Mixed Content?

When a user accesses a page served over HTTP, their connection can be vulnerable to eavesdropping and man-in-the-middle (MITM) attacks. In contrast, visiting a page served over HTTPS ensures an encrypted and authenticated connection with the web server, protecting against such attacks.

However, when an HTTPS page includes embedded HTTP content, it becomes susceptible to interception or modification by malicious entities. This situation of mixing secure and insecure content is known as "mixed content". As a result, the webpage is only partially encrypted, leaving some content exposed over HTTP. To address this risk, browsers implement a Mixed Content Blocker to restrict certain HTTP requests on HTTPS pages.

In my case, resolving the issue involved adjusting the jQuery includes to remove the protocol, like so:

<link rel="stylesheet" href="//code.jquery.com/ui/1.8.10/themes/smoothness/jquery-ui.css" type="text/css">
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.ui/1.8.10/jquery-ui.min.js"></script>

A temporary workaround would be to disable protection on the affected page, though this is not recommended due to security implications.

UPDATE: For further insights into mixed content issues and how to handle them, you may refer to this resource from Mozilla's support pages:

If necessary, you can allow the mixed content to display by following these steps:

Click the shield icon labeled Mixed Content Shield in the address bar and select Disable Protection on This Page from the dropdown menu.

An orange warning triangle Warning Identity Icon will indicate the presence of insecure content being loaded.

To reverse this action and re-block mixed content, simply reload the page.

As a side note, I tested the code provided above in CodePen and it worked without any issues.
