No Tracking with SSL

Are you using a self-signed certificate? In this case you should try to use the “Disable SSL peer verification” switch (Settings -> WP-Piwik -> Piwik).

Or is the problem just about the tracking (i.e., the stats dashboard is shown, the site is estimated, etc.)? If you are running a blog without SSL and Piwik with SSL, you should try to use the “force protocol” option and choose “https” (Settings -> WP-Piwik -> Tracking).

Please also check if your tracking code is properly added to your site. If you are not sure, open your site’s source code and copy & paste the Piwik tracking code which is added to your site (please post in between backticks).
