 * WordPress refuses to activate the plugin because it triggers a FATAL ERROR:
 * > Fatal error: Cannot redeclare GuzzleHttp\uri_template() (previously declared
   > in /public_html/xxx/wp-content/plugins/comet-cache-pro/src/vendor/guzzlehttp/

 * Hi [@ginmi](https://wordpress.org/support/users/ginmi/)
    Could you test it again,
   with the latest plugin version? (1.0.5)? We were working on fixing this problem,
   so now it should be OK.

 * Tried activating on a test site and the plugin generated an error 500 as soon
   as it’s activated.
 * Clearly the plugin is not yet ready for a production site.

 * Hi [@ginmi](https://wordpress.org/support/users/ginmi/),
    A lot o people already
   use the plugin. The error message 500 is quite generic, and can be caused by 
   many reasons, depending on your environment configuration. Could you please share
   with us a bit more details?
 * Cheers,
