Excuse me if this has been addressed before, but I only found 1 post about this that was closed.
I'm using Headwaytheme which has the option for gzip compression. If the option is activated I receive a "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error."in Chrome. A similar message in FireFox:"The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression."
