I'm using TwentyTen and have made a lot of changes to the style.css file and several of the php files to customize my blog.
After just updating to 3.0.4, the design has reverted almost completely back to the default settings.
How do I get all the design edits I made over the past several weeks reactivated? I don't even know all the files I've changed anymore. However, I did do a full backup before the upgrade.
Please help with suggestions. Thanks.
