How to set up HTTPS for WordPress

Setting up HTTPS
Removing insecure content

In this article we will provide you with basic steps regarding making your WordPress website working via a secure web protocol and some methods of removing insecure content which is preventing the “green padlock” to show when an SSL certificate is installed.

The first and only requirement before proceeding with this guide is to have an SSL certificate activated and installed for your domain on our hosting server.  So let's start with enabling https://

 Setting up HTTPS

In order to make WordPress fully secured, you will need to adjust your WordPress Address (URL) and Site Address (URL) accordingly (

You can do it in your WordPress Admin Dashboard > Settings > General menu:


From now on, all your WordPress website pages can be accessible via https:// links.
Now you also need to force all links automatically redirect to https://.

You can do this either by adjusting the WordPress inner redirect structure, which we don’t recommend, or simply by installing one of HTTPS plugins designed for this purpose.

We will use Easy HTTPS (SSL) Redirection in order to force all pages over https:// connection. You can install it in Plugins > Add new menu:

Once it is downloaded and activated, go to the Settings > HTTPS Redirection menu. Check 'Enable automatic redirection to the "HTTPS"' and 'Force resources to use HTTPS URL' options. Click on Save Changes button:

NOTE: The plugin may be incompatible with other scripts, so in case of any redirect loops or other issues, try deactivating other plugins first (caching and protecting ones) or changing the theme to a different one.

Removing insecure content

Your website may be visited via link after the SSL certificate installation, but it is still possible that you have insecure http:// links inside your pages.

Such links will prevent the padlock from appearing, and you will be getting messages regarding insecure content. These issues are resolved by replacing such links with their secured versions.

Locating such links can be difficult if you have a large website with many pages. However, you can use third-party online tools which could locate such links by scanning your website:

In this example, we used WordPress with an SSL certificate installed and one of free themes from the web.

When https:// is used, issues with insecure content appear:

Apart from online checkers, most of the modern browsers also provide developer tools which can give you the same information.

For example, in Chrome, you can enable this tool by right-clicking on your page > Inspect element. In the console below you can see warnings about insecure elements:

This tool will provide you with the list of insecure links on your website. However, finding their location can be hard in case of complex websites like WordPress.
In this example links to insecure fonts and stylesheets are present.

Since the default WordPress installation does not contain insecure links and content, the theme is most likely causing the issue. In order to resolve it, find insecure links in the theme scripts and replace them with secured analogues.
If you don’t know where exactly these links are located, you can use the search cron command below or run the same command in CLI via SSH:

      grep -r "http://" /home/cPuser/public_html/ > /home/cPuser/report.txt

(make sure you replace cPuser with your actual cPanel username)

NOTE: Setting up a cron job to run with the interval of less than 15 minutes may cause account resource overuse.

Once the search is finished, you can check the report.txt file where all scripts/files containing insecure http:// links will be specified. Here is an example of the output:

'std' => '',


   /home/nctest/public_html/https/wp-content/themes/thbusiness/functions.php: wp_register_style('googleWebFonts', ',700,400italic');

As you may see, all results are coming non-filtered, meaning that not related lines will be present as well, so you will need to either enhance the search command with regular expressions for a more precise search or closely inspect results as they are.

In raw results we can see the insecure link to fonts:,700,400italic

which should be changed to:,700,400italic

in /wp-content/themes/thbusiness/functions.php file.

NOTE 1: Not every link will work after its change to https://, so before making any changes we suggest backing up the original file in order to restore it later if needed.

NOTE 2: You can also use plugins (e.g., SSL Insecure Content Fixer) for updating CSS and JavaScript http:// links.

Fortunately, updating the font link in the functions.php file was enough to resolve the issue in this example:

In most cases however, the number of such links is greater as they can also be located in plugins and other scripts of the theme in use.

Most of user-added content links are stored in the database.

In the next example Inspect tool shows that the insecure link to an image is causing the issue.

We will find and replace it directly in the database:

NOTE: We strongly recommend creating a backup of the database before making any changes.

You can search through the database via cPanel -> phpMyAdmin application:

1. Select the database of your website (it can be found in wp-config.php or the file stored in the website root folder).

2. Select Search and input http:// (you can also try searching for the exact link specified in Chrome -> Inspect tool ) as the search pattern.

3. Select all tables and click Go:

4. You will get a number of results from all the tables. Usually, insecure links are stored in posts/pages so search through them first:

5. On the next page, you should see all database cells containing the search pattern, look through their content to locate the http:// link to the external resource and replace it with the https:// version:

 This should yield the desired results:

If something is not working correctly after enabling https://, we suggest rechecking if any active plugin/extension/theme/template is causing the issue and if so, contact its developer for assistance with https:// implementation.

That's it!
