WordPress CDN Enabler plugin settings

A lightweight WordPress CDN plugin to link your assets to a content delivery network (CDN).

  1. Create a Pull Zone in the KeyCDN dashboard.

  2. Install the CDN Enabler plugin (log in to your WordPress dashboard: Go to Plugins -> Add new).

  3. Activate the plugin and click on settings.

  4. Enter the CDN URL or Zone Alias in the CDN Enabler Settings (you can find the CDN URL in the KeyCDN dashboard):

    Note: The CDN URL needs to start with the same protocol as your website (e.g. http:// or https://). CDN HTTPS needs to be enabled if your website is using HTTPS.
  5. Save the settings and verify in the HTML code if your assets are loading from the CDN.

In Settings > General, make sure to use an HTTPS URL if HTTPS is used for the CDN as well. If your blog is located in a certain path (e.g. ) it needs to be updated accordingly as shown in this screenshot:

Note: If your Site Address is different from your WordPress Address defined in Settings > General, follow the instructions below.

Some WordPress installations may not be located in the root directory but rather within a sub folder such as the following:

In this case, the CDN Enabler's Included Directories settings need to be configured to account for this. The difference in path from the Site Address to the WordPress Address must be prepended to the directories which contain the files you want to be integrated with KeyCDN. In the above example, site is the only difference between both URLs, therefore your CDN Enabler settings should resemble the following.

Purging KeyCDN cache from the dashboard

CDN Enabler also allows you to purge your KeyCDN Zone's cache directly from the dashboard. This means no more having to log in to the KeyCDN dashboard to purge the cache whenever need be. To configure this feature simply navigate to CDN Enabler's plugin settings and add your API Key and Zone ID.

To retrieve your KeyCDN API Key, log in to the KeyCDN dashboard and navigate to Account > Authentication. Copy your secret API Key and paste it into CDN Enabler's settings field. Next, navigate to the Zones tab in your KeyCDN dashboard and copy the Zone ID of the website you are accelerating. Paste this into KeyCDN Zone ID field within the plugin's settings.

You should now be able to purge that Zone's cache by clicking the Purge CDN button located in the top admin bar.
