 * I’m trying to update WordPress to 4.0 but when I press re-install it just throws
   me an error and when I try the manual download there is an error as well – Page
   not found… What should I do and is it only me or someone else has this problem?
   Thanks.

 * There should be an upgrade button. You only need to re-install if you had a failed
   installation, not to upgrade.

 * Ok the next day it randomly started to work perfectly… But I have another problem
   why I even wanted to install it in the first place… My category pages shows me“
   404 page”. Before I used different theme in which the category pages worked but
   now it doesn’t how could I fix that?

 * Try re-saving your permalink structure at Settings/Permalinks in your admin panel.
   If WordPress cannot automatically edit the `.htaccess` file, it will provide 
   manual instructions after saving.
