[Plugin: WordPress.com Popular Posts] Permalinks now using https in Popular Post widget after 3.1 up

Just upgraded to WordPress 3.1 today, and now the permalinks in the Popular Posts widget are using https rather than http. I don’t have an SSL certificate, and don’t want to use https.

Is anyone else experiencing this problem? Is there a workaround?

You can see this in action on any of the Popular Post links on the sidebar on this page: https://www.jeffhester.net/2011/02/08/apqc-2011-knowledge-management-conference/
