I just installed WP Social SEO Booster v1.0.1, created a free Kraken account (and activated it via the email link), and entered my username, password & key into the WP Social settings, which I've double checked. But it's not working.
The "Optimize it now!" link in the Media tab does nothing. And new uploads are also not optimized.
Has anyone else seen such a problem? Does anything more need to be done?
