Problem upgrade 3.8.5

[dimmicosacerchi]

I'm not sure I understood, but I'll explain what I did.
I uploaded all files in the upload folder with my ftp program, except the install folder.
Before carimento files, I renamed the file config.php.new in config.php (and I've entered the data in my database).
I uploaded all the files and the contents of folders (in the appropriate folders).
When I finished, I went on: http://www.dimmicosacerchi.it/forum/...nalupgrade.php and, despite the error appeared:

Your vBulletin (3.8.4) Does Not Appear To Be Running That was the downloaded version (3.8.5).

This Was Not Generally MEANS your upgrade successful. Please ensure That You Have uploaded the latest files and click here to try again.

If you are sure you wish to continue with this part of the upgrade, click here.

I did all the steps, without success.
