I have tried changing the 'Showcase' theme colors through Admin, but it does not work, the color changes are saved in the Admin, yet do not show on the site. I have tried clearing the cache, changing define('OW_DEV_MODE', false); to true and back to false, but no luck, is there something else I have to do?

And you did this on the else option and you pressed f5 on your page?

Try clearing your DNS cache as well. Sometimes you can get locked on a DNS cached version as well.
