This error message is due to the fact that we received a positive response from the API, but the output of the content from your website contained additional and unexpected data.  This can be caused by a third-party plugin that has superseded our attempts to obtain the output buffer, or by a gateway or CDN reverse proxy (such as Cloudflare or Ezoic) that is injecting its own content into the response.

In any of these scenarios, the ability of our plugin to serve an optimized cache will be broken.   You should not proceed with the installation.
