Error occured. Disable WP HTTP Compression plugin if you have it enabled ?

[dice]

I got this message after entering the API key and ID
Error occured. Disable WP HTTP Compression plugin if you have it enabled

Does anyone know what this is about because I've no idea what WP HTTP compression is?

Thanks

Do you have WP HTTP Compression plugin installed on site? Specify please button which you press, and page link where you got an error.
