texas_smoke69, Yes, you should use an FTP host to manually put the updated version of http.php in the wp-includes folder on your server. FileZilla is free and a decent FTP client.

zncjmom, that should take care of the duplicate declarations, but in my case I had a lot of files that didn’t fully update, so I received one “redeclared” or “undeclared” error after another, and manually updated my files until there were no other errors. I read that the WP automatic updates don’t always fully work, depending on your plugins and themes.

Both the older and newer versions of http.php are in wp-includes, but the code changed to not define the class WP_Http, since it is defined in the new file class-http.php (which was not included in previous WP installs). So in my case, I updated and got the new class-http.php file, but my http.php file did not update…so I did it manually.

I had the same problem, and I fixed it by manually downloading WordPress 3, and then uploading the new version of http.php which is in the folder /wp-includes. The older version defines the class WP_Http (hence the “redeclare”), but the new version does not.

Hope that helps!
