 After successfully upgrading Wordpress, on the "Upgrade Wordpress" page
 the system returns me with the following errors:

 Warning: gzinflate() [function.gzinflate]: data error in
 ...wp-includes\http.php on line 1787

 Warning: gzuncompress() [function.gzuncompress]: data error in ...\wp-
 includes\http.php on line 1792

 if i exit the page and i come back the errors are not longer there.

 I have read all the threads in the Wordpress forum and my wordpress has
 got no virus and has not been hacked.

 if i automatically reinstall Wordpress, only one error is shown:

 Warning: gzuncompress() [function.gzuncompress]: data error in .../wp-
 includes/http.php on line 1824

 at the end of these error there is the following statement:

 WordPress upgraded successfully

 I have got this error since Wordpress 2.8. Since then i have always
 upgraded manually. However i am worried , is this anything major happening
 on my blog or not.

 can i still automatically upgrade despite the errors?
 does it have to do with something broken in my WP or is it a WP bug?

 I have tried to disable all my plugins but the error is still there.

 my plugins are:

 Akismet, All in One SEO Pack, CommentLuv, Contact Form 7, Get Recent
 Comments, Google XML Sitemaps, Hello Dolly, Let It Snow! , Simple Tags,
 Translate, Viper's Video Quicktags, WP-PostRatings, WP-Print


 Thanks to anyone who will reply to me!
