Antoligy MyBB Cloudflare Management Plugin Not Working

[MI-6]

So the plugin named "Antoligy MyBB Cloudflare Management Plugin" doesn't work and gives me this error:

Fatal error: Cannot redeclare Cloudflare_menu() (previously declared in [redacted]/inc/plugins/Cloudflare.php:29) in [redacted]/inc/plugins/Cloudflare.php on line 37

Anyone know how I can fix this?
