Before you take any steps please backup your site and database (just to be sure).

1) Install W3 Total Cache plugin to your WordPress blog:

  • Log into your WordPress administration section
  • Go to Plugins and click on Add New. There are two ways how to add the plugin:
    • Download the W3 Total Cache plugin from website  (You don’t need to unzip this file)
    • Click on the Upload link in the top navigation bar
    • Click on the Choose File button and browse to the W3 Total Cache plugin you downloaded
    • Click on the Install now button to install the extension into your website


    • Click on the Search link in the top navigation bar
    • Type W3 Total Cache in the input and click on Search Plugins
    • Select Install now
  • Click on “Activate” to run the plugin.

2) Configuring the W3T plugin with our CDN:

  • In the side menu find the Performance tab and click on it to open W3T main configuration
  • Scroll down to the CDN section
  • Check “Enable” and select “Generic Mirror” from “CDN type” drop down
  • Click “Save all settings” as shown in the image:

  • In the side menu under Performance or in the horizontal menu at top of the page click on CDN link.
  • Scroll down to the “Configuration” section and enter your CDN url in the input “Replace site’s hostname with: “. (You will find the url on the page CDN list in CDN77 client section).
  • Click “Save all settings“.

  • Go back to General settings. Click on the “Deploy” button, then on “Save all settings” as shown in the picture:

Note: If by clicking on Deploy you are forwarded to this page: “WordPress Failure Notice”. With content: Are you sure you want to do this? Please try again. Click on Please try again. Now you should see a yellow header at the top. Click on the Deploy button in that instead.

You are now using CDN!
