ERR_CONTENT_DECODING_FAILED when logged in

Apr 21 at 4:20 PM
I've just upgraded to the latest version 3.3.5.0.
When I'm logged in, some pages in my blog (only some pages, not all) give the error ERR_CONTENT_DECODING_FAILED.
If I'm not logged in, such pages works and are correctly visible. Only when I'm logged in as Admin or Author I got such an error.

How can I fix that?
