Opencart on HTTPS

Hi,
The site on opencart 2.3.0.2. Translated site to https - missing statistics collection. Other sites (not opencart) are working correctly - the statistics are collected. Used piwik 2.17.1, hosted on a third-party site (not opencart). What could be the problem?

Hi,

Is the Piwik instance also reachable via HTTPS.

Otherwise, tracking is impossible as insecure content isn’t allowed in secure websites.

If it is, can you check the javascript console when you open your website. Is there any error?
