If you cannot install or upgrade Comet Cache Pro via the WordPress Dashboard (perhaps because your web hosting company is blocking the requests to WebSharks' servers; see Why am I getting a 404 error?), then you may need to use FTP/SFTP to install or upgrade Comet Cache Pro.

Follow these steps to install or upgrade Comet Cache Pro via FTP or SFTP:

  1. If you are upgrading Comet Cache, visit WordPress Dashboard Comet Cache Plugin Options Plugin Deletion Safeguards first and make sure that "Safeguard my options" is selected; this will ensure that you don't lose any of your existing Comet Cache configuration when upgrading.
  2. Deactivate and delete Comet Cache, if it is currently installed.
  3. Download the comet-cache-pro.zip file from your account at cometcache.com.
  4. Unzip the file you downloaded; you should now have a folder called comet-cache-pro.
  5. Login to your site via FTP/SFTP and navigate to wp-content/plugins/ (if you're not sure how to do this, please contact your web hosting company).
  6. If there is an existing comet-cache-pro folder inside wp-content/plugins/, delete it (or you can overwrite it with the new folder).
  7. Upload the new comet-cache-pro folder (the one you unzipped) to wp-content/plugins/
  8. When finished uploading, visit WordPress Dashboard Plugins, locate Comet Cache Pro in the list of installed plugins, and click Activate on Comet Cache Pro.
  9. Once the plugin is active, you can go to WordPress Dashboard Comet Cache Plugin Options Enable/Disable, and Enable Comet Cache.

That's it! The latest version of Comet Cache Pro has now been installed or upgraded.
