Hmm, I can’t see it either – but _ck_ mentioned that her gzip plugin usually isn’t needed in most cases?

Also, the bb-gzip plugin is only necessary if your server does not already compress pages, which is rare these days, so make sure you are not duplicating the effort.

Maybe you could get away with disabling the bb-gzip plugin, which would hopefully resolve the problem?
