I am upgrading to 1.5.2 at the request of my host, who says the previous 22.214.171.124 compromised the host. I see the Codex directions, but is there a shorter route when upgrading? Where would that be?
Also, my sidebar.php in the default theme has extensive mods in all three of my wordpress blogs. Can I keep this file in updating in the blogs or do I have to reedit all of these sidebar files?
