Re: default templates being used
With 0.8, we still use the my-templates and my-plugins directories. What you need to do is create a directory for your theme that you have and put it in the my-templates directory:
Then, what I did was copy all the files from the default theme into my directory folder that I hadn’t changed to make a complete template folder. For example, if you changed only style.css, header.php, front-page.php and footer.php, then copy the rest of the files from the default template into that folder as well.
Once you have all those files in your theme directory, go to the admin => presentation => and pick your theme! It works pretty slick. You may want to take a snapshot of your theme and upload it so that the admin area knows which one it is! Uploading a snapshot with the name screenshot.png should do the trick!
EDITED NOT TO START CONFUSION!
