If you get the error Glyphicons-halflings-regular.woff2 while working with the Glyphicon font, don’t miss today’s blog. We are going to bring you an overview of Glyphicon as well as the solution to this problem. Let’s get started now!
An in-depth look at Glyphicons
As you know, Bootstrap includes three main files which help you manage all the features of the website and user interface. They are Bootstrap.CSS, Bootstrap.JS, and Glyphicons. Today, we will explore the third file, Glyphicons, in a clear and detailed way.
Glyphicons are known as font icons that appear in website projects to help site visitors navigate or access the data on a website. All of them can be edited in color and size. Glyphicons Halflings comes with 260 available and free glyphicons in Bootstrap. They are used in various formats, such as text, toolbar, button, form, navigation, and so on.
By using Glyphicons for your website, you can avoid using images as icons. As a result, you can make your site more attractive and load faster.
Normally, a glyphicon can be inserted into a website via the following syntax:
<span class=”glyphicon glyphicon-name”></span>
The glyphicon-name value must be changed to a suitable name for the glyphicon.
Why does the Glyphicons-halflings-regular.woff2 error occur?
When you are using Bootstrap 3 and trying to add glyphicons to your website project, have you ever faced the error Glyphicons-halflings-regular.woff2 not found? So, what are the reasons?
First of all, this issue may happen because IIS only recognizes certain valid file types and does not recognize the .woff or .woff2 extensions. Therefore, it responds to requests for these files with a 404 not found error.
In some cases, you can also see the error because you did not download all the Glyphicons Halflings files. If you miss any file in the fonts folder or CSS folder, the Glyphicons-halflings-regular.woff2 error may appear.
Furthermore, this error sometimes appears when you include the wrong path or the wrong format when you load the font. To understand this better, let’s take a look at the following example. If you bundle bootstrap.css along with some other files as ~/bundles/css/site while your font files are in ~/fonts, bootstrap.css will translate and look for your glyphicon fonts in ~/bundle/fonts. That path is wrong.
These are the three most common reasons for the Glyphicons-halflings-regular.woff2 error, so let’s move on to the next part to explore the solutions together.
How to fix the Glyphicons-halflings-regular.woff2 error
In order to fix the error caused by the first reason, you just need to add the following code lines to your web.config project:
<system.webServer>
...
</modules>
<staticContent>
<remove fileExtension=".woff" />
<mimeMap fileExtension=".woff" mimeType="application/font-woff" />
<remove fileExtension=".woff2" />
<mimeMap fileExtension=".woff2" mimeType="font/woff2" />
</staticContent>
Alternatively, you can add more MIME types to solve this problem. Let’s follow the 3 simple steps below:
- Firstly, on your IIS project home page, you need to click the MIME Types button to open it.
- After that, simply press the Add button in the Actions menu.
- Now, there will be a window in the middle of the screen allowing you to add more MIME types. So, it’s time for you to fill in the file name extension including .woff and .woff2. The MIME type will be application/x-font-woff and application/x-font-woff2.
If you tried the first method but the error is still there, you should check all the files. If you recognize that there is a missing file, simply download this missing file and then add it to the right folder. The error Glyphicons-halflings-regular.woff2 will be fixed.
Finally, in case the error is caused by the third reason, it’s a good idea for you to rename the folder to make sure all the files are bundled in the right path.
