Errors in 2.8 and 2.8.1

This is honestly rediqules. nothing but trouble since i have upgraded to 2.8 and not any better with 2.8.1

i keep getting these errors.

Warning: gzinflate() [function.gzinflate]: data error in /homepages/20/d159566430/htdocs/jericocom/store/wp-includes/http.php on line 1787

Warning: gzuncompress() [function.gzuncompress]: data error in /homepages/20/d159566430/htdocs/jericocom/store/wp-includes/http.php on line 1792

I also get random re-directions from the wp-admin to a “https://vasthtml.com/wp-admin/undefined” url.

The WordPress.com Stats plugin has stoped working, the Wp-Forum plugin is useless since i can no longer access the admin menus for the plugin.

Should have stayed with 2.7.1.
