Recently, we upgraded techknowl to use it with MAXCDN content delivery network. The MAXCDN service has complete compatibility with WordPress and is one of the cheapest CDN available for bloggers. The addition of a CDN to wordpress is pretty much simple. However, it’s simpler with a plugin called W3 total Cache. Apart from the easy CDN integration, W3 total cache includes several features that will improve the speed and response of a WordPress blog. Earlier we were using WP Super Cache plugin -along with a combination of a few other plugins for our caching requirements. Now we have uninstalled all those plugins and migrated to W3 total cache plugin and MAXCDN service.
We should uninstall and delete all WP- Super Cache files before starting with W3 total cache. However, we cannot delete WP-super cache directly from the WordPress dashboard. If tried, it will show an error ” UNINSTALL-WP SUPER CACHE must be set to a non- blank value in uninstall.php” in a new window. The process fixing this very easy if you have FTP or cPanel access to your WordPress blog files. In cPanel, Open file manager and browse to WordPress installation wp-content>plugins>wp-super cache> and select to edit uninstall.php.
As shown in the screenshot, change the value in the quotes to “1” and save the file. Now open your web browser and enter yourdomin.com/wp-content/plugins/wp-super-cache/uninstall.php.
Click on uninstall button to remove WP Super Cache completely from WordPress files.
After this you can download and migrate to W3 total cache from the WordPress plugin directory. This plugin has a lot of options and advanced configurations. All options are self explanatory and easy to understand. The plugin page itself gives a quick idea about Database Cache, Browser Cache, CDN, Page Cache and Object Cache so that you can choose and enable the required ones. More details on MAXCDN configuration on W3 total cache will be given in our next article.
